The Washington State Department of Transportation (WSDOT) reports that travelers on northbound I-5 will soon see a new electronic sign above the highway at Tumwater Boulevard in Thurston County.
A weekend of overnight closures is needed to remove the old sign and lift the new 1,900-pound sign into place.
Overnight Friday, March 20 and Saturday, March 21, WSDOT maintenance crews will close all lanes of northbound I-5 at Tumwater Boulevard from 10:00 p.m. until 7:00 a.m. the following morning.
Northbound I-5 will reduce to a single lane approaching exit 101 for Tumwater Boulevard. Travelers will use that single lane to detour around the closure using the off- and on-ramps at Tumwater Boulevard.
Tumwater Boulevard Overpass Closure
Both directions of Tumwater Boulevard over I-5 will also close during the work:
- Westbound Tumwater Boulevard will close at the northbound I-5 on-ramp.
- Eastbound Tumwater Boulevard will close at Littlerock Road.
- Southbound I-5 travelers using exit 101 will detour to Littlerock Road.
All southbound l-5 lanes will remain open.
The highway closure ensures no vehicles will travel directly below the work zone on Tumwater Boulevard, where crews will use a large truck and crane to maneuver the massive sign into place.
WSDOT Needs Help from Travelers:
- Consider rescheduling discretionary trips around work hours.
- Add extra time to help prevent delays.
- Expect reduced speeds and congestion approaching the work zone.
More I-5 Lane Closures Ahead
From Monday, March 23 through Thursday, March 26, northbound I-5 travelers can also expect overnight single lane closures at the Tumwater Boulevard overpass from 10:00 p.m. until 5:00 a.m. the following morning while crews complete electrical work for the new sign.
