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

Project overview

This project replaces the 1965 southbound I-5 Puyallup River Bridge. The new bridge is built to current seismic standards and will be straighter and wider than the previous bridge.

The project also modifies the Port of Tacoma Road on-ramp to southbound I-5, demolishes the existing old I-5 bridges over the Puyallup River, demolishes and rebuilds the East L Street overpass that crosses I-5, replaces existing concrete pavement from McKinley Avenue to Portland Avenue, upgrades signing, illumination, stormwater collection facilities, and water quality treatment facilities.

Once finished, this project will open HOV lanes in both directions on I-5 from SR 16 in Tacoma to Fife.

What to expect

During the overnight hours of Thursday, Dec. 2, Friday, Dec. 3 and Saturday, Dec. 4, construction crews will set 15 girders total for the new East L Street overpass. This work will require full directional closures of I-5 in Tacoma during overnight hours. During overnight hours of Thursday, Dec. 2, all lanes of southbound I-5 will close from the Bay Street/Portland Avenue exit through Tacoma. On Friday, Dec. 3 and Saturday, Dec. 4, all lanes of northbound I-5 will close during overnight hours from the northbound I-5 exit 133 near South 38th Street. Travelers will follow signed detours using SR 509 and I-705. Travelers are also encouraged to use alternate routes around Tacoma on those nights such as SR 18, SR 167 and SR 512.

Leading up to the girder setting work in early December, travelers can expect overnight lane and ramp closures on I-5 and SR 167/Bay Street, daytime, overnight and around-the-clock closures of 20th Street East in Fife. A long-term closure of East L Street overpass in Tacoma is still in place.

Travelers will see shifted travel lanes and temporary exit relocations. They will also see a temporary regulatory speed limit reduction to 50 mph on I-5 in place. The speed limit reduction for this project on northbound I-5 begins at milepost 133.06 and continues to milepost 136.19. The speed limit reduction on southbound I-5 begins at milepost 136.67 and continues to milepost 133.86.

This project builds a new southbound I-5 Puyallup River Bridge.
