This intersection currently operates at LOS F for the SBLT movement, and has for many years. A signal warrant analysis was done in 2017, originally for the intersection of Southcenter Blvd and 62nd Avenue S, but given the close proximity of these intersections, bookmarked on either end by signalized intersections, signalization is warranted - and recommended - at 65th Avenue S. Doing so will 1) Provide a safer crossing for pedestrians utilizing the King County Metro bus zone on the south side of Southcenter Blvd (the zone provides service for Rapid Ride F-Line and Rt 150 - the workhorse of South King County). 2) Improve overall intersection operations. 3) Provide gaps in traffic to aid intersection operations at the 62nd Ave S intersection. 4) Aid in controlling existing high speeds on Southcenter Blvd. 5) Improve operation for the new Fire Station 52, located just north of the intersection, by providing signal override through Opticom for the fire truck and aid cars.
