SR 530 and Smokey Point Blvd Temporary Signal

Project Description

The City of Arlington is placing a temporary traffic signal at the intersection of Smokey Point Boulevard and SR - 530 in October 2019.  This temporary traffic signal will remain in place until a steel-pole span wire signal can be installed.

This signal system will remain as the City continues to work with WSDOT and stakeholders on the long-term solution: installation of a roundabout.

Design of the roundabout is currently underway.
