The next phase of the SR169 Traffic Improvement is relocation of a Puget Sound Energy main gas pipe, located at SR169 and Roberts Drive in Black Diamond. Due to being on a state highway, the City will be working with WSDOT.
This project will impact local traffic. To avoid major traffic impacts, the construction will take place at night. Construction started Sunday, February 25, 2024. You can expect one lane closures with alternating traffic. The work hours will be 7:00 p.m. to 5:00 a.m. The City is projecting construction to last 4 weeks, with weather depending.
