TACOMA, Wash. – Thousands of drivers will be impacted by a major closure of a southbound Interstate 5 exit in Tacoma.
The South 38th Street exit (#132A) will close at 12:01 a.m. Saturday and remain closed through July as part of the Washington State Department of Transportation's Nalley Valley Viaduct Project.
WSDOT estimates nearly 10,000 cars use this ramp daily, which provides access to many area businesses, including Costco and the Tacoma Mall.
Transportation officials warn that drivers could see back-ups as long as five miles on southbound I-5 during peak commute times, from 6:00 a.m. to 9:00 a.m. and from 3:00 p.m. to 6:00 p.m.
A detour will direct drivers to the South 56th Street exit (#130), according to WSDOT. From there, drivers will be able to re-enter northbound I-5 and take the northbound exit for South 38th Street.
Crews will demolish, rebuild and realign the exit ramp. The new ramp will be higher and wider to accommodate the new eastbound State Route 16 viaduct.
