Description: Contractor crews for the SR 520 Portage Bay Bridge and Roanoke Lid Project are using the staging site just south of Fuhrman Avenue and west of Eastlake Avenue for equipment deliveries and storage.

Traffic: To help with delivery of equipment and materials, parking alongside Fuhrman Ave. just north of the staging lot is restricted on weekdays from 7 a.m. to 3 p.m. beginning June 15 until further notice.

Please note: This area is heavily congested with multiple construction projects including the RapidRide J Line Project. Crews working for the Portage Bay Project are only using this lot as staging and are not closing streets on Eastlake Avenue or otherwise restricting access in this area beyond the staging lot and this section of parking.

If you have concerns with parking availability, please call our 24-hour construction hotline at 206-319-4520. If you have questions about other construction on Eastlake Avenue, please contact those projects directly.
