Decade-old HOV project in Tacoma about to enter home stretch

In February, widening will begin on southbound Interstate 5 between the Tacoma Dome and Port of Tacoma Road to make room for new HOV lanes. The final $324 million segment is part of a $1.6 billion project that is expected to finish by fall of 2021.

In February, widening will begin on southbound Interstate 5 between the Tacoma Dome and Port of Tacoma Road to make room for new HOV lanes. The final $324 million segment is part of a $1.6 billion project that is expected to finish by fall of 2021.

Pierce County’s decade-old HOV project is about to enter its home stretch. But don’t expect to use those diamond lanes until fall of 2021.

In February, a contractor for the state Department of Transportation will begin widening Interstate 5 between the Tacoma Dome and the Puyallup River to make room for the new HOV lanes.

In order to accomplish that a new bridge to carry the southbound lanes of I-5 will be built. Then, the old bridges will be demolished.

The final $324 million segment between the Dome and the Port of Tacoma Road is part of the $1.6 billion overall project which is adding the HOV lanes in Pierce County and essentially rebuilding stretches of I-5, WSDOT said.

Once this final segment is completed, HOV lanes will open in both directions of I-5 through Tacoma. Carpools and buses will be able to travel on HOV lanes from Gig Harbor to Everett, WSDOT said.

Narrowed lanes — from 12 feet to 11 feet — on other segments of the ongoing road construction project through Tacoma have led to numerous crashes involving semi-trucks. The most recent was on Wednesday.

During the project, I-5 drivers can expect:

Narrowed and shifted lanes and ramps.

Demolition of the L Street overpass and construction of a new overpass.

Nighttime lane and ramp closures.

Occasional weekend and longer ramp closures.

The HOV lane construction project in Pierce County began in 2009.
