166th Avenue NE has been re-striped to provide one through lane in each direction, a center turn lane with intermittent medians for traffic calming purposes, and bike lanes on both sides of the street. Additionally, the contractor has completed signal modifications on 166th Avenue NE to add a protected left turn onto westbound NE 85th Street. At NE 95th Street and NE 91st Street rectangular rapid flash beacon (RRFB) systems have been installed to provide safe pedestrian crossings. Radar feedback signs have been installed in the school zone near NE 91st Street to assist with traffic calming.

Project Background

166th Avenue NE is a major corridor between Education Hill and Downtown Redmond. It also provides neighborhood access to Education Hill schools and churches. To accommodate all modes of transportation and address known safety concerns, Redmond’s Comprehensive and Transportation Master plans called for the conversion of 166 Avenue from four lanes to three. Rechannelizing 166th Avenue NE between NE 85th and NE 100th Street completed the conversion of the corridor.

Key intersections included 166 Avenue NE at NE 85 Street, at NE 95 Street, and at NE 100 Street. Safety issues that required consideration included delay to side street vehicles accessing 166 Avenue NE, sight distance deficiencies, a truck climbing lane, collisions, traffic speed and volumes, and pedestrian crossings.
