2.  Main Street Revitalization – Substantial Construction on 236th Street SW for July & August

Main Street Construction Update, 236th Street SW Substantial Construction Began July 8: The Main Street Revitalization Project construction work on 236th Street SW and 56th Avenue W is ongoing and on schedule. The week of July 8, significant roadway construction work began on 236th Street SW; this work is expected to take between 4 to 8 weeks to complete. During this period, all roadway users should expect the following:

The road surface of 236th Street SW from Gateway Boulevard to 56th Avenue W has undergone asphalt grinding. 236th Street SW has been reduced to one-lane of travel with flaggers controlling the direction of traffic between westbound and eastbound travel. Drivers should expect to travel on gravel. In addition, travel on 236th Street SW between 56th Street SW and 58th Street SW will be westbound traffic only. Drivers should use the signed detour routes or take an alternate route that may be more convenient. As construction progresses during this period, the city will provide additional construction information that is up-to-date and reflects the contractor’s progress.

Tour de Terrace Traffic Changes: The current detour route that takes drivers north of 236th will be flipped to the south for the weekend of Tour de Terrace to avoid conflicts with the parade.

Night work for utility crossings on the WSDOT controlled portion of 236th has been completed.
