Burnside Bridge Earthquake Readiness Project

Seems like this would be the perfect time to address West Burnside and turn it into a one way couplet with Couch extending from the East Side over to the West side of the river. Especially if the bridge is replaced, the alignment could be shifted to allow the existing bridge to be used during construction. Shift it somewhat north and transition Couch/Burnside on each side onto the bridge and make them a couplet on both sides.
Or go crazy and build a bridge a city block wide with roads at the boundaries and a new bridge park that connects the West and Eastside waterfront parks with a greenspace bridge across the river. Just have to get rid of that pesky road on the eastside that is in the way. |
I think the main thing about the Burnside bridge worth keeping are the cool castle-like towers. I'd think those could be removed and stored somewhere for re-attachment to a replacement bridge.

How is it possible to have no mention of the Marquam bridge in that report? Did I miss it? I did a search but didn't find it in there. Is the plan to have it collapse so we can then start from scratch and get something less god awful?

Yikes.
Don't watch that video before bedtime. |
My reaction was, yep, that is pretty much what I already knew. I am hoping we can secure funding for a new Burnside Bridge soon for this very reason.

Found this presentation given a few months ago. It looks like options of preserving the bridge or a seismic retrofit are being ruled out, with only a complete rebuild or hybrid (rebuild of major portions of bridge and approaches) likely to move forward.
Slide 42 shows some options for a rebuild on the current alignment, or alignments to the north and south. It's hard to imagine either of those moving forward given the impacts they'd have at the approaches. |
