As previously reported, two of West Seattle’s smaller bridges are set for earthquake-resistance work soon. Bidding has just closed for one, and opened for another:

DELRIDGE PEDESTRIAN OVERPASS: We reported last month that bidding had opened for this seismic project. As of today, it’s closed. The city had listed the project budget as $5 million; the three “base bids” range from $2.3 million to $3 million. They’ll be vetted before the contract is awarded. Once a contractor is chosen, the construction schedule will be worked out; previously, SDOT has estimated the work could last up to a year.

ADMIRAL WAY (FAIRMOUNT) BRIDGES: Bidding just opened today for this project (technically two bridges), summarized on the bidding website as follows:

The seismic retrofit of the Admiral Way Bridges includes the following general items of work: strengthening of steel column bents, new bracing at concrete pier bents, retrofit of bridge deck joints, bridge abutment retrofit, slope stabilization, strengthening with Carbon Fiber Reinforced Polymer (CFRP), and steel painting.

The project also is summarized here (though obviously the construction timeline mentioned there didn’t happen; SDOT told us last spring they were aiming to complete it by the end of this year). As for cost, this 2023 presentation cited a 2020 estimate of $15 million. Bids are due February 21st.

Regarding the Admiral Way project, I wonder if this will require closing Fairmount to cars and pedestrians? I know this project is at least a few years in the future, but I don’t see how they can keep Fairmount open for most of the project schedule.

The project website linked in the article says,

“A temporary, full street closure at the bridge on SW Admiral Way.

“A full street closure below the bridge on Fairmount Ave SW for the duration of construction.”

i hope they are keeping an eye on the Schmitz Park bridge too. It is old.

Last time the Admiral Way bridge underwent a retrofit the contractors dumped the leftover rebar and other debris (including the project announcement sign!) into Fairmount Ravine instead of disposing of it properly. This new bid request needs to stipulate that cleanup will be part of the project requirements.

I believe that was the result of a storm. (the sign one) because I remember that happening when I lived by there during the retrofit.

Sorry, comment time is over.
