The Maple Park Avenue entrance to the Plaza Garage will be partially closed from about 7 a.m. to 7 p.m. on Thursday, Oct. 23.

A concrete mixer truck will be parked near the parking garage entrance that day as part of a project, overseen by the Department of Enterprise Services, to repair and reconstruct two stair towers and an elevator in the parking garage structure.

The truck will not block the nearby entrance to the Department of Transportation building underground parking garage. In addition, a traffic flagger will help drivers and pedestrians navigate safely around the concrete truck and work area.

The stair tower project will repair the structural integrity of the concrete beams and panels at the western entrance of the Plaza Garage off of Capitol Way. The project also entails reconstructing stair towers 1 and 8 — the ones nearest to the Employment Security Building — and replacing the elevator in stair tower 1.

For many years, water has been penetrating the surface of the East Campus plaza undermining and weakening the garage and infrastructure below. Corrosion from the moisture has escalated structural deterioration at the western entrances where structural beams, concrete walls and ceiling panels are loosening, creating a growing public safety risk to users.

During the project, state employees who park in the southern portion of the Plaza Garage should use stair tower 2, which has an elevator, or 7 to get access to the upper East Plaza.

The project is scheduled to be finished in June 2015.
