I-5 - Slater Road Interchange - Improvements

Project overview

WSDOT is starting work on the Slater Road corridor north of Bellingham, between Rural Avenue, west of I-5, and Northwest Drive, east of I-5. These improvements are broken into multiple phases and the projects will relieve congestion on the I-5 off ramps at the Slater Road Interchange. This will include the implementation of roundabouts and improvements at the Slater Road northbound ramp terminals.

Winter 2020 - Fall 2024
Project status
$8 Million

What to expect

During construction, travelers can expect a two week long closure of the on-ramp from Slater Road to I-5 and off-ramp from I-5 to Slater Road.
