72 Hours to Safety: Rainier Avenue Rechannelization

The best way to transform a four-lane road into a two-lane neighborhood street: implement it over one weekend. Visit one of Seattle’s most ambitious road rechannelization projects, the Rainier Avenue corridor project, which rechannelized a principal arterial with up to 26,000 vehicles per day, taking it from four lanes to one lane in each direction, with a center turn lane. The project improved safety for everyone by reducing speeds, improving pedestrian crossings, and ordering turning movements at intersections. On this tour, learn about the data analysis behind the engineering decisions, the extensive community outreach in one of the country’s most diverse neighborhoods, and the planning and teamwork behind completing most of the installation over 72 hours.
