FOLLOWUP: Terminal 5 railroad ‘quiet zone’ construction finally about to start, SDOT says

More than a year and a half after Terminal 5 started accepting cargo shipments at its first modernized berth, a long-delayed related project is finally starting construction. SDOT sent a notice today announcing that work is expected to start next week for the railroad “Quiet Zone” that once was intended to be in place before the berth opened. (This new announcement is four months after SDOT had last said construction was imminent.) Here’s SDOT’s summary of the “Quiet Zone”:

The project, located along W Marginal Way SW from Chelan Ave SW to SW Dakota St, aims to reduce train horn usage in this area by building a new traffic signal; closing some railroad crossings; and upgrading safety equipment at other railroad crossings. The project will also provide safe and accessible ways for people biking/walking to access destinations near Terminal 5 and will include building a bike/pedestrian mixed use trail along West Marginal Way SW where there is currently no sidewalk.

According to the notice, most work will be done on weekdays, and there will be some “temporary lane closures” on West Marginal, as well as some temporary parking restrictions. SDOT told us back in March that construction would last about a year, and the contractor is Merlino Construction.
