BELLINGHAM: Northbound I-5 lane and on-ramp closure planned Wednesday night, March 11, for maintenance

Northbound Interstate 5 will be reduced to a single lane and the Iowa Street on-ramp to northbound I-5 will close Wednesday night, March 11, in Bellingham.

People traveling through the area should expect delays from 10 p.m. Wednesday, March 11, to 4 a.m. Thursday, March 12, during the lane reduction near milepost 253. Drivers also should seek alternate routes during the Iowa Street on-ramp closure at the same time.

WSDOT maintenance crews will repair a guardrail and perform vegetation work.


SEDRO-WOOLLEY: SR 9 remains closed at SR 20 until damaged railroad crossing repaired

State Route 9 will remain closed between SR 20 and West State Street/Trail Road (milepost 55) in Sedro-Woolley until repairs are made to a rail crossing signal box damaged in a crash Nov. 1.

The signals box, which facilitates safe operations of the railroad crossing, is owned by BNSF Railway. It was damaged beyond repair. We also own equipment that must be replaced and are coordinating this effort with BNSF. Crews made temporary adjustments to signal timing on SR 20 while the intersection is closed.

There is no estimate for the roadway to reopen, but you can use West State Street/Trail Road as a short detour around this closure.


Construction, maintenance and special events

Road work ahead

We often have special events and roadwork taking place in the Northend, including construction projects, maintenance and repairs. We always try to minimize any effects to travel, but sometimes it is necessary to close a lane to do the work or create a safe work zone for our crews.

If you spot our crews, slow down and give them space to work! A huge thanks to our crews for all their hard work.
