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

Project overview

This project replaced 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 modified the Port of Tacoma Road on-ramp to southbound I-5, demolished the existing old I-5 bridges over the Puyallup River, demolished and rebuilt the East L Street overpass that crosses I-5, replaced existing concrete pavement from McKinley Avenue to Portland Avenue, upgraded 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

The partial closure of the Portland Avenue and East 27th Street intersection in Tacoma has been canceled for the weekend of March 3-6. We will provide an updated closure date once it is available.

At 9 a.m. Sunday, Aug. 28, Guy F. Atkinson Construction crews opened the final 3-mile section of southbound Interstate 5 HOV lanes in Pierce County. The new lane connects the existing HOV lane running from Seattle to Fife with the one that stretches from Tacoma to westbound State Route 16 in Gig Harbor.

On Friday, Aug. 19 the new East L Street Bridge over I-5 reopened to travelers. The original bridge was removed so I-5 could be widened for HOV lanes.

As of Friday, April 1, all southbound travel lanes are on the new southbound I-5 Puyallup River Bridge. Five out of six new southbound lanes are open for travelers, including four general purpose lanes and an auxiliary lane.
