Drivers traveling between Skagit and Snohomish counties need to prepare for weekend delays and backups as crews work to rehabilitate two southbound Interstate 5 bridge decks.

Washington State Department of Transportation contractor crews from Graham Construction will repair the bridge deck on two separate sections of southbound I-5 over the weekend. One section is near the Skagit/Snohomish county line and the other is south of State Route 532. This work is part of a two-year interstate improvement project between Conway and Arlington.

Lane closure details
• 10 p.m. Saturday, Aug. 24, to 8 a.m. the morning of Sunday, Aug. 25: the two left lanes of southbound I-5 over the Pilchuck Creek Bridge, south of exit 212/Stanwood/Camano Island will close for restriping. The right lane will remain open.
• 8 a.m. Sunday, Aug. 25, to 6 a.m. Monday, Aug. 26: the right lane of southbound I-5 at milepost 211 will close. The left two lanes will remain open but will be shifted away from the work.
• 1 p.m. Sunday, Aug. 25, to 6 a.m. Monday, Aug. 26: the southbound I-5 off-ramp to 236th Street Northeast will close. Crews will have a signed detour in place.
• 10 p.m. Sunday, Aug. 25, to 6 a.m. Monday, Aug. 26: the two left lanes of southbound I-5 at milepost 217, just south of the Skagit/Snohomish county line, will close. The right lane will remain open.

Drivers using this stretch of I-5 Sunday night into Monday morning should be aware of two separate work zones and a reduced speed limit of 55 mph south of SR 532.
During the closures, crews will add a new waterproofing barrier and fresh asphalt on the bridges. While the forecast looks favorable, this work is weather-dependent.
The longest delays are expected Sunday afternoon, Aug. 25, and could last into the evening hours. Travelers can help reduce backups and delays by adjusting travel plans around this closure. If you must travel, consider:
• Leaving before or after peak travel periods.
• Using a carpool or vanpool.
• Riding transit.
Drivers between Skagit and Snohomish counties should continue to plan for single lane closures during the day and double lane closures overnight, until this project wraps up in fall 2019.
