According to a news release:
Drivers can expect up to a 2-mile backup and four nights of double-lane closures, reducing southbound I-5 between Lacey and Tumwater to a single lane.
Work is set to begin Monday on two I-5 southbound lanes between Martin Way and Tumwater Boulevard. It’s set to begin at 9 p.m. and continue until 6 a.m., depending on the weather.
Crews will switch to the northbound lanes in the same area during the week of Oct. 8.
The purpose is to improve visibility for drivers by striping with methyl methacrylate, a more durable, plastic-like material that lasts longer than paint.
The work requires overnight closures so the old paint can be removed and new striping can be applied.
