I-5 - Portland Avenue to Port of Tacoma Road - Southbound HOV - L Street overpass

Design-build contractor Guy F. Atkinson Construction closed the East L Street overpass in Tacoma to pedestrian, bike and vehicle traffic at 12:01 a.m., Monday, March 25, 2019 until fall 2021.

  • The closure allows crews to demolish and rebuild the overpass to accommodate a widened Interstate 5 and new HOV lanes.
  • The new East L Street overpass will sport two 11-foot-wide lanes for vehicular traffic, flanked by two six-foot-wide sidewalks and bicycle lanes in both directions.


During the closure, drivers, bicyclists and pedestrians will follow the following detour routes:

Vehicle and pedestrian detour for the L Street overpass in Tacoma

During the closure, vehicles and bicyclists will detour using East 28th Street, East Portland Avenue to East 27th Street and Wiley Avenue, to East McKinley Way and East 34th Street.

A pedestrian detour will be available via East 28th Street, East Portland Avenue and East 27th Street.

Construction timeline

In April 2019, Guy F. Atkinson Construction crews removed the old East L Street overpass in Tacoma.

Since then, crews widened Interstate 5 and built new bridge piers at both ends of where the new overpass will be.

There are several construction milestones ahead of us before crews can build the center bridge pier for the new East L Street overpass. Some of those milestones include:

  • Finish the new southbound I-5 Puyallup River Bridge
  • Replace the original roadway surface on I-5 from the Puyallup River Bridge up to East L Street matching into the previous projects pavement limits

Once those milestones are reached, crews can begin building the new East L Street overpass center bridge pier.

In addition to building the bridge structure, crews will be making improvements to the East 28th Street and East 27th Street intersections. The work includes making modifications to intersection pavement, sidewalks, and curbs and gutters at both locations and will require some local street closures. Crews hope to begin this work sometime summer 2021, but an official date has not yet been identified. We will share that information once we have it.
