A major step in our I-5 improvement project in Tacoma is about to start, but so is a 7-month closure of a key exit, and we need drivers to be prepared for some potential delays during peak traveling times.
Starting as early as 11 p.m. Friday, April 14, our contractor crews building HOV connections between I-5 and SR 16 will close the northbound I-5 exit to Tacoma's city center – exit 133 – for 7 months. That means drivers who use this exit to reach downtown Tacoma, I-705 and SR 7 will need to use a detour onto the northbound I-5 exit to SR 16 and Tacoma Mall (exit 132), around the clock. While it's a pretty simple detour, we do expect backups at peak commute times so drivers should plan extra time to their trips.
During the closure, crews will build new northbound I-5 lanes, a new northbound I-5 bridge and a new northbound I-5 off-ramp to Tacoma's city center. They'll also start building new HOV lanes for both eastbound and westbound SR 16 traffic merging onto I-5.
This is the third of three projects designed to improve the I-5/SR 16 interchange and provide a direct connection to HOV lanes between the two highways.
We know that anytime we close lanes or exits, it's an inconvenience for drivers but the only way to get this major portion of the project completed in a timely and safe manner is to do this full closure. We appreciate your ability to adjust and be patient while this work gets done.
