I-5 - Slater Road Interchange - Improvements

WSDOT is starting work on a project to improve the Slater Road corridor north of Bellingham, between Rural Avenue, west of I-5, and Northwest Drive, east of I-5.

Traffic studies show the Interstate 5/Slater Road (Exit 260) and surrounding interchange will experience more traffic due to rapid growth in the area within the next decade.

In 2014, WSDOT built compact roundabouts to better manage congestion and improve safety on this corridor. Those interim roundabouts have successfully and safely kept traffic moving but they are due for an upgrade.

Using practical design principles, WSDOT engineers will work with people who use this corridor to understand the traffic problems they experience. Based on that feedback, WSDOT will create multiple design options. WSDOT will then work with community residents and area partners to narrow down those designs to a preferred alternative that improves identified problems and stays within the project’s Connecting Washington budget.
