Drivers heading on to southbound Interstate-5 from Trosper Road in Tumwater, will need to follow a signed detour when the ramp closes for 24 hours, beginning at 11 p.m. Saturday.
The signed detour will reroute drivers to Littlerock Road or Capitol Boulevard to exit 101 on Tumwater Boulevard. The southbound off-ramp lanes will not be affected during this work.
Crews plan to replace an existing concrete storm pipe, re-grade and place new asphalt throughout portions of the ramp. They will also be installing a new drainage system as part of a project funded by Walmart Stores, Inc. that widens the southbound I-5 on- and off-ramps, adds another dedicated left-turn lane and creates a dedicated thru-lane at Trosper Road.
Work should be wrapped up by 11 p.m. Sunday.
