Removing Barriers: Converting Culverts to Bridges for People & Wildlife

- Undersized, damaged, aging culverts can limit access to important stream habitat for fish and other aquatic organisms. They can also seriously affect transportation if a culvert fails or negatively impacts the road above.
Replacing a culvert with a larger, more suitable structure like a bridge is a win-win for fish, water quality, transportation, and the economy. At Peterson Creek, a tributary to the Miami River in Tillamook County, Oregon, upgrading the undersized, perched culvert improved access to 6.2 miles of upstream habitat for ESA listed coho salmon, as well as Chinook, chum, steelhead, cutthroat and lampreys.
The project also creates substantial transportation and safety benefits for the community by improving the Miami-Foley Road alignment and elevating the roadway above 100-year flood levels. Miami-Foley Road is a critical transportation and emergency route for Tillamook County.
Tillamook Estuaries Partnership has been working directly with Tillamook County Public Works to implement the Peterson Creek Fish Passage Restoration this summer, which is a Salmon SuperHwy Priority Project.
Trout Unlimited, NOAA Fisheries Service, Oregon Watershed Enhancement Board, Oregon Department of Fish and Wildlife, U.S. Fish and Wildlife Service, and the U.S. Forest Service have provided funding and in-kind support for this project.
One of the fascinating hydrologic aspects of the culvert was its effect upon the larger river that the stream flowed into. Much like air forced through a straw, the water flow from the culvert formed a faster higher pressure flow that created a "scouring" effect downstream of the river, altering the rivers overall flow pattern and bottom structure.
Nice to see the culverts coming out, Here in Alberta many such projects are underway or have been completed to restore natural flows and migrations to rivers and creeks. nice work guys keep up the good work.
This makes me wonder what Newfoundland's situation is like. Where I live we have a salmon ladder near by. But we've been building damns every few decades and I fear not being as fish friendly as we should be.
A cracking video, & such a well meaning crusade for the protection & assistance of wildlife.
Encouraging to see projects like this. Well done.
Great that the salmon can now pass, but I'm very sad to see at 7:08 that virtually no shoulder was provided for anyone not in a vehicle to use this brand new bridge. This bridge will likely stand for a century and will for its lifetime be a barrier to humans outside of vehicles, ironically similar to how the culvert was for the salmon.
Seriously. a great way to help the environment is to encourage people to walk and ride bikes... this does the opposite
Maybe they didn't want to encourage human traffic in a sensitive salmon spawning zone? Attracting fishing activities.
Hopefully this bridge is for the salmon and not for the heavy trucks loaded with timber cut from the mountains around Miami River.
This is absolutely brilliant and it just shows you, if all people just do one thing like this it makes such a positive impact all over the world. So just remember your small efforts actually do create a huge impact 🙌🏻
Some places use rectangular section pre-cast concrete culverts, to keep the construction time down but still keep the flow velocity low.
Mind you, I don't know anything about how the soil/rock geology determines whether that's feasible.
Most places in the Portland area of Oregon use that form of Culvert. Though here, they use it specifically "prevent flooding", and no other reason. In the hood where I grew up in Aloha, there is a creek called Butternut Creek that runs through it, and they exclusively have used concrete rectangle culverts since the mid 2000s as the homes built near and next to it would often experience flooding, thus the roads would become impassable for a few days to a week or so at a time. But you can clearly see despite the lessened impact on velocity, they're still altering the overall pathing and health of the stream.
Beautiful improvement. Thank you🐠
I'm so glad to learn about this project! So beneficial all the way around!
Really cool to watch, thanks for showing us all the progress.
Good luck with the continued replacement of culverts. Let's hope that it just becomes systematic, identify or locate a culvert, put it on the schedule for replacement. NO need for studies, just do it when funds become available, funds which should be part of scheduled road and culvert maintenance.
Ronald Newton telling me about the tonnes of weight. Perfect name for the job!
This is amazing! Thank you for working to perverse our wildlife!
Good job! Smart thinking!
Very interesting to see! I have a culvert at the base of my property (near Clatskanie, Oregon) and I'm curious what your process was to get the different municipalities on board for the project. Also curious if there is any way to see if a given creek has historically had salmon/trout runs. I don't see fish in our creek these days, but it's a year-round creek that has more than enough flow for them and it would make me extremely happy to see them reintroduced. (I've also been looking into relocating beaver to our property.)
That is so cool.
It only cost _________?
Full respect and admiration for your work. I wish you success. I hope it leads to other ares doing the same thing. Unless it's for storm drains, metal culverts should not be used.
Cool project!
Integrity of the Bridge is, of course paramount, yet upstream responses could impair the Bridge with very high flows, and additional debris or bank collapses, large woody debris and bedload to test its span and clearance.
I'm pretty sure if the culvert lasted as long as it did that bridge wont have any issues.
My only concern is the lack of any vegetation on the loose rock, gravel & dirt embankments at the base of the bridge structure. Over time, that will get eroded pretty heavily without some kind of natural reinforcement like grasses and small ground-cover and shrubs.
@@TheCriminalViolin The bridge is ancored with deep piles. A lot of material can be eroded before there is any danger to the bridge. And if it's a healty stream you will have erosion, but also new material coming from upstream.
It looked funny but was nice to watch these big burly men taking so much care with the little salmon fry.
Yes, that was cool. It reminded me of "Seven Years in Tibet."
Well done guys!
Great work. Thank you and keep it up!! 🥰
forward thinking. good job all.
Very cool!
Great idea people's, it's on the bears menu too , helps them get fat ! 🐾💝🐻🐾🐾🐾🐾
Great work.
Thx.
🇺🇸🇺🇸🇺🇸🇺🇸☮️
This culvert replacing is such a good program! The salmon need access to habitat , including the upper Snake river in central ID. Free the Snake!
So fantastic ❤
Whats the difference between the second bridge they built and the first one that traffic is going over?
I keep seeing these videos and they mainly seem to be in Oregan. Seems like such a cool state, I want to come visit someday
cool
Just to clarify, this bridge will last many many many years weighing many many many many pounds so that many many many many salmon can breed and many many many many many people in the community can cross safely? ...... many.....
Culverts act a venturies and drop barriers.
With its stunning Views and amazing diversity of Species which rely on riverine/stream based inputs, outflows, to redirect Opportunities for broader Transportation requirements to withstand existing Requirements as to, also, afford release of flows to contribute to yearly recruitment of Anadromous fish Species and should also allow for Class Arthopoda, crustaceans, wetands diversity and functioning continue to process anadromus or migrational patterns of existing organisms to reproduce.
Was this translated from another language?
I love The random Capitalization of certain Words.
It doesn’t look like a fish can go up that stream, looks to shallow
I've always thought culverts are just cheaper than bridges. It's a lazy way to allow water to travel. So glad that more and more my species is considering the needs of other species. Thank you.
Thank you for having a brain...
Be sure to monitor for large woody debris flows that might be possible to destroy or disable Functions, or see that Maintenance and Pre-highwater peaks are reviewed for such Inputs or dialogue and the immediate Affects on Structure's Inegrity.
The water volumes of upland drainages, creeks, gulches or Individual inputs, necessitates the hydrological flow cycles inferred by Historical and Natural Records which need to oversight as new Conditions scour and deposit in various reaches of the downstream reaches.
So you’re telling me you have to drive 90 foot plus piles to foundation for the bridge and that’s as cheap or cheaper than a culvert? Sounds like a lot of creative finance.
Bridges are much more costly to build and maintain than culverts. I would rather see a culvert anywhere it is possible to eliminate bridges. This idea of bridging culverts may sound like a good idea when there is grant money available for the new build, but road departments never have the budgets needed to adequately maintain the bridges after they are built. A six foot culvert may cost under $10,000 to install. That bridge will be in the hundreds of thousands.
Think about how much money we can save if we just did away with biodiversity and wildlife. /s
If you americans fix your suburbian sprawl issue, you'll get more funds for infrastructure
@@MFgr8 i'm pretty sure you can design a culvert without creating a barrier. Choose a slightly bigger one, make sure there is a threshold downstream to always keep a sufficient level of water without a drop, allow for some sedimentation, don't build it too long.
Should fix all the issues without needing an expensive, non-recycleable concrete bridge with huge piles driven right through the formerly undisturbed water-guiding sediments that make up the riverbed.
It's not like building a bridge won't have negative impacts.
No solution fits everywhere, and actively thinking is much more useful than just knowing.
A bit sad that non-profit private organization has to push for something that government is suppose to do.
Post10 does not approve 😄
The idea of a culvert instead of a bridge is stupid in the first place. 😮
If the culvert is big enough, it doesn't really make a difference, does it?
You can allow for sediment, low velocity and a minimum water level even with a culvert, unless i misunderstand the word culvert itself.
A few thousand dollars vs a few million, yeah, that's stupid!
biggest scam i have seen in a long time (we were able to save 2 coho juveniles -- most expensive fish per lb ever) same two i caught one year later for dinner. Note all you had to do was turn the elliptical shaped culvert on its flat side and the velocity would be less , by the way during flood season such restrictions hold up water flow -- you know like beaver dams. we are trying to restore. do salmon successfully jump beaver dams? we must destroy all beaver damns! I can see it now
Never trust anyone talking ... "community."
Jesus Christ is the Son of God who died for our sins and God the Father raised Him from the dead on the 3rd day. He loves us more than anyone. He created us and loves us. His blood was shed for us for forgiveness of sins. Repent and Call upon His name! Heaven and Hell are real places. The Kingdom of God is at hand. Only Jesus Christ can save our souls.
“Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost. For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call.” Acts 2:38-39 KJV
“From that time Jesus began to preach, and to say, Repent: for the kingdom of heaven is at hand.” Matthew 4:17 KJV
“Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.” John 14:6 KJV
“He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him.” John 3:36 KJV
“For if ye forgive men their trespasses, your heavenly Father will also forgive you: But if ye forgive not men their trespasses, neither will your Father forgive your trespasses.” Matthew 6:14-15 KJV
“And I say unto you, Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you. For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened. If a son shall ask bread of any of you that is a father, will he give him a stone? or if he ask a fish, will he for a fish give him a serpent? Or if he shall ask an egg, will he offer him a scorpion? If ye then, being evil, know how to give good gifts unto your children: how much more shall your heavenly Father give the Holy Spirit to them that ask him?” Luke 11:9-13 KJV
“And he spake this parable unto them, saying, What man of you, having an hundred sheep, if he lose one of them, doth not leave the ninety and nine in the wilderness, and go after that which is lost, until he find it? And when he hath found it, he layeth it on his shoulders, rejoicing. And when he cometh home, he calleth together his friends and neighbours, saying unto them, Rejoice with me; for I have found my sheep which was lost. I say unto you, that likewise joy shall be in heaven over one sinner that repenteth, more than over ninety and nine just persons, which need no repentance.” Luke 15:3-7 KJV
“And as it is appointed unto men once to die, but after this the judgment: So Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation.” Hebrew 9:27-28 KJV
“And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst. But I said unto you, That ye also have seen me, and believe not. All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out. For I came down from heaven, not to do mine own will, but the will of him that sent me. And this is the Father's will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day. And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.” John 6:35-40 KJV
“In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through Him, and without Him nothing was made that was made. In Him was life, and the life was the light of men. And the light shines in the darkness, and the darkness did not comprehend it. There was a man sent from God, whose name was John. This man came for a witness, to bear witness of the Light, that all through him might believe. He was not that Light, but was sent to bear witness of that Light. That was the true Light which gives light to every man coming into the world. He was in the world, and the world was made through Him, and the world did not know Him. He came to His own, and His own did not receive Him. But as many as received Him, to them He gave the right to become children of God, to those who believe in His name: who were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God. And the Word became flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth. John bore witness of Him and cried out, saying, “This was He of whom I said, ‘He who comes after me is preferred before me, for He was before me.’ ” And of His fullness we have all received, and grace for grace. For the law was given through Moses, but grace and truth came through Jesus Christ. No one has seen God at any time. The only begotten Son, who is in the bosom of the Father, He has declared Him.” John 1:1-18 NKJV
“that word you know, which was proclaimed throughout all Judea, and began from Galilee after the baptism which John preached: how God anointed Jesus of Nazareth with the Holy Spirit and with power, who went about doing good and healing all who were oppressed by the devil, for God was with Him. And we are witnesses of all things which He did both in the land of the Jews and in Jerusalem, whom they killed by hanging on a tree. Him God raised up on the third day, and showed Him openly, not to all the people, but to witnesses chosen before by God, even to us who ate and drank with Him after He arose from the dead. And He commanded us to preach to the people, and to testify that it is He who was ordained by God to be Judge of the living and the dead. To Him all the prophets witness that, through His name, whoever believes in Him will receive remission[b] of sins.” Acts 10:37-43 NKJV
“And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell. Are not two sparrows sold for a farthing? and one of them shall not fall on the ground without your Father. But the very hairs of your head are all numbered. Fear ye not therefore, ye are of more value than many sparrows.” Matthew 10:28-31 KJV
“Whosoever therefore shall confess me before men, him will I confess also before my Father which is in heaven. But whosoever shall deny me before men, him will I also deny before my Father which is in heaven.” Matthew 10:32-33 KJV
“That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. For the scripture saith, Whosoever believeth on him shall not be ashamed. For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him. For whosoever shall call upon the name of the Lord shall be saved.”
Romans 10:9-13 KJV
“Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God. That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.” John 3:5-6 KJV
“Who hath delivered us from the power of darkness, and hath translated us into the kingdom of his dear Son: In whom we have redemption through his blood, even the forgiveness of sins: Who is the image of the invisible God, the firstborn of every creature: For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him: And he is before all things, and by him all things consist. And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence. For it pleased the Father that in him should all fulness dwell; And, having made peace through the blood of his cross, by him to reconcile all things unto himself; by him, I say, whether they be things in earth, or things in heaven.” Colossians 1:13-20 KJV
“Look not every man on his own things, but every man also on the things of others. Let this mind be in you, which was also in Christ Jesus: Who, being in the form of God, thought it not robbery to be equal with God: But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men: And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross. Wherefore God also hath highly exalted him, and given him a name which is above every name: That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth; And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.”
2 Philippians 2:4-11 KJV
And lo, The Flying Spaghetti Monster spoke, and she said ‘Fish passage is cool.’ And all was well.
