Building two-way Mercer

The Mercer Corridor project is “shovel ready”. Design is 100 percent complete and ready to advertise for construction bids as soon as final funding is approved. The City plans to provide an eight-week period for contractors to put together their bid packages. By moving forward with the project as soon as possible, Seattle expects competitive bids in the current economic climate. A construction management firm is already under contract. Due to the magnitude and complexity of this project, as well as the volume of traffic that will be managed during construction, the City has prepared detailed construction staging plans in order to ensure consistent bids and help support public outreach planning efforts. This staged construction approach minimizes impacts to users of the corridor and keeps people and goods moving.

Construction Stage 1

In Stage 1, the Seattle Department of Transportation (SDOT) will construct new westbound lanes along the north side of existing Mercer Street.

Construction Stage 2

During Stage 2, the new lanes will serve existing eastbound traffic, while east-bound Mercer Street is rebuilt in its new location. Major east/west flow will be minimally interrupted.

Construction Stages 3 & 4

Following completion of Mercer Street construction, all through travel lanes operate on Mercer while Valley Street improvements are constructed.

Seattle will enforce both federal and state prevailing wages and fringe benefits (see agency certification). When the federal and state wage rates differ, the higher wage rate will be required. Seattle already has an on-the-job training program aimed at developing trainees from disadvantaged populations to journeyman status. Training and promotions of members of certain minority groups and women is a primary objective of this program.
