SR 525 Widening and Safety Improvements - Photos

Drivers benefit from a four-lane, divided SR 525 between I-5 and Mukilteo
We widened a six-mile segment of SR 525 between I-5 in Lynnwood and Paine Field Boulevard in Mukilteo to four lanes.  We also built a new interchange at SR 525 and SR 99, which improved drive times and safety on these popular commuter routes.
