New Sellwood Bridge | Completed
Some Sellwood Bridge replacement choices...

I like Cable-Stayed and Delta-Frame a LOT.
|
I like the cable stayed a lot as well. Thats one type of bridge portland doesn't have yet that i'd like to see. But, since this is portland and good design rarely wins out we'll probably end up with the box girder.
|
In addition to the Cable-Stayed, I like the Through Arch.
|
pdxman, it's Sellwood. They'll demand the through arch, even if every other bridge option is cheaper and dropped money on them as they crossed it.
|
The nice thing about the through arch is that you don't have pillars in the middle of the river like with all the other designs.
|
definitely cable stayed or through arch
|
Deck do look good, I agree with others.
|
I dont like the cable stay mostly because it seems like every new bridge that is being built is one of those...other than that, I have nothing against it being a cable stay...which is what will probably be chosen.
|
The costs of each option get larger from top to bottom, so from a cost-benefit point of view, the Delta Frame would be my choice. If cost wasn't a factor (lol), of course I'd prefer the Cable-Stayed. The Through Arch looks too similar to the OC-West Linn Bridge and the Fremont Bridge.
|
I like the Delta Frame the most... keeps in tune with the original design and keeps the sight lines up top open.

Article from the Oregonian today...

How can anyone possibly give a 100% guarantee that a bridge (or any other structure) won't fail? |
I rode my scooter over the bridge a few weeks ago... probably the first time I had ever been over it.
Wow. That is one sketchy bridge! It would make an ideal pedestrian or bike bridge, but even on a scooter (25 mph) it felt way too small and rickety. The lane widths and lack of shoulder space or sidewalks in particular. Quote:

Any news?

I know it’s an important project in the Portland area, but “one of the biggest infrastructure projects being contemplated on the West Coast”? Not sure about that. Some drawings from the project website… http://www.sellwoodbridge.org/ Alternative D http://www.sellwoodbridge.org/Bridge...ternativeD.jpg Alternative E http://www.sellwoodbridge.org/Bridge...ternativeE.jpg |
D, please
|
Am I reading the above article correctly? It seems to contradict itself....The bold type states that Plan D would be a 2 lane bridge replacing a 2 lane bridge. Plan E would be a 4 lane bridge (including transit) replacing the 2 lane bridge. Then farther down in the article the options appear to be opposite. Am I blind or not understand something here?

And California is starting a $40 billion dollar High Speed Rail project. And Seattle is considering at least 2, maybe more, multi-billion dollar projects. And SF is..... oh never mind. Stick to facts, Wheeler, not hyperbole. |
Task force OKs $300M Sellwood Bridge plan
Task force OKs $300M Sellwood Bridge plan
A community task force approved a $300 million plan Monday to replace the aging Sellwood Bridge. The new bridge would require the demolition of four condos to the south of the existing bridge and one townhouse to the north. The new bridge would be approximately 30 feet to the south of the existing bridge, which would remain open during construction. The plan now needs approval by a group of elected and appointed leaders that includes representatives from the city of Portland, Multnomah County, Metro and TriMet. That group will meet next Monday to review the task force recommendation. It is expected to approve the plan in a second meeting on Friday, Feb. 6 at 3 p.m. at the Multnomah County building. If approved, the Federal Highway Administration would then need to sign off on the project, a process expected to take at least one year. Construction could begin in 2012. The price tag is calculated in 2012 dollars. Funding for the project remains unclear. “Funding is the million dollar question,” said county spokesman Mike Pullen. “It’s probably not a project that will get money from the proposed federal stimulus package because it’s not a shovel-ready project.” The community task force that made the recommendation includes a cross-section of business and community leaders. The existing bridge is in need of major repairs or replacement. It has a rating of 2 out of a possible score of 100 from the National Bridge Inventory. To put that in perspective, the Minnesota bridge that collapsed in 2007 had a rating of 50. http://portland.bizjournals.com/port...9/daily21.html |
I find it incredible that the Sellwood Bridge could cost 1/3 of a billion dollars to replace.
I am glad to see some more movement on the project though. |
