FERNDALE, WA (MyBellinghamNow.com) – Drivers should expect delays on the highway north of Bellingham over the next few weeks.

The Washington State Department of Transportation (WSDOT) says the southbound I-5 on and off-ramps at Slater Road in Ferndale will be closed for two weeks starting Thursday, Sept. 26.

Crews are working to realign the southbound off-ramp to Slater Road to support the new two-lane roundabout that is being built. The project currently needs more dirt to build up the ramp embankments.

Signed detours will be in place to guide drivers around the closures.

Once the ramp closures end, there will be single-lane closures on Slater Road on weeknights from 8 p.m. to 6 a.m. until construction of the new roundabout finishes in early 2025.

In the meantime, anyone traveling in the area should plan for extra time and delays.
