Roadwork and Maintenance closures


1st Street Bypass

City council awarded the 1st Street Bypass construction contract on Monday, May 13, 2019 to Scarsella Bros., Inc., in the amount of $12,947,526.86. From Kent, WA, Scarsella is well qualified to build the new arterial, having built many similar projects.

The bypass project includes widening 1st Street from (2) lanes to (5) lanes, between State and Alder, and will extend 1st Street as a (2) lane bypass from Alder to 47th Avenue. The roadway improvements will include a shared-use path, illumination and traffic signal improvements. With completion of WSDOT’s interchange project at SR529 in 2022, the bypass will provide important commuter access to I-5, and allow them to bypass congestion on 4th Street and the BNSF crossing.

There will be significant construction traffic on 1st Street between State Avenue and Alder Avenue, and on 47th Avenue, to support this work. 

No parking is posted on 1st Street from State Ave to Alder Ave. 

UPDATE 3-5-20:  With initial paving completed last week to the south of 1st from State to Alder, traffic has moved from the north side to the south side of 1st St. Utility and roadway work has started on the north side of 1st Street. Residents are directed to use 1st Street Alley for access during this time, with the exception of existing driveways, which will remain open. 1st Street between Columbia and Alder will remain closed.

Due to construction that has started on 47th Ave NE, commuters and residents are advised to avoid 47th Ave NE, south of 3rd Street at this time. The roadway is still open to 2-way traffic with one narrow lane in each direction. If use of 47th Ave cannot be avoided, please Giv’em a Brake and move cautiously through the construction area. Pavement demo is currently underway, with subgrade materials to be installed on Saturday, to allow paving to start next week on Monday. In addition, a concrete pour is also scheduled on Monday near the industrial park, which will also affect traffic. These operations are expected to extend through next week. Thanks for your patience, please avoid 47th if possible, and be safe!

We appreciate your patience during this important project. We will do our best to minimize impacts to the community, and to build the City an exciting new roadway project. Please contact Steven Miller, Senior Project Manager at 360.363.8285 or with any questions or concerns.
