Before we move on from traffic to today’s other news – one more weekend alert: The 1st/Olson work at the east end of the SW Roxbury corridor continues. This project began without a standalone announcement and we’ve been asked what it’s going to accomplish, so we asked SDOT’s LeAnne Nelson, who explained:
The 1st/Olson location was prioritized for a Levy to Move Seattle major maintenance rebuild, to enhance reliability and function where underground wiring/materials had degraded. The failing existing conduit system had caused repeated maintenance issues.
The 4-intense-weekends-effort was planned to reduce traffic impacts during replacement of underground wiring and bonding across about 70 feet of travel lanes. Crews finish installing the new underground infrastructure this weekend, followed by paving. The new conduit connects to our Traffic Operations Center and Intelligent Transportation System, which helps enhance safety and mobility remotely.
There is an additional phase of the effort, above ground, expected to be complete by the end of September. It includes new LED traffic signals and new signal support poles—better aligned with the current roadway configuration for optimal visibility.
Interesting side note, the team had to make minor adjustments to the planned conduit route, after discovery of an abandoned streetcar rail during excavation. (Photo above)
