Nickerson Street Changes
Revised February 27, 2012
In the summer of 2008, The Seattle Department of Transportation (SDOT) removed three marked crosswalks along Nickerson Street. These crosswalks were removed because they no longer met national guidelines for unsignalized marked crosswalks. When the crosswalks were removed, SDOT made a commitment to the community that we would evaluate other pedestrian improvements along the corridor – including a possible rechannelization.
After completing a traffic analysis of Nickerson Street - taking into consideration traffic which may shift to this corridor due to the North Tunnel Portal of the Alaskan Way Viaduct project and construction of the Mercer West Corridor, SDOT determined that there is minimal impact and the rechannelization project was completed in the summer of 2010.
Travel lanes on Nickerson Street (from 13th Avenue West to Florentia Street) were reconfigured to improve pedestrian safety and increase driver compliance with the speed limit. SDOT also added two new marked crosswalks and monitored traffic speeds over the next year.
The year following the rechannelization saw a 23 percent reduction in collisions over the preceding five-year average. The project improved traffic safety by dramatically reducing the percent of drivers traveling more than 10 miles per hour over the speed limit. The percent of drivers traveling over the speed limit has been reduced by more than 60 percent, and top-end speeders have fallen by 90 percent. Meanwhile, traffic volume (including freight) remains roughly the same as it was before the rechannelization, with no evidence of traffic diversion.

This project is part of the “Bridging the Gap” transportation levy approved by Seattle voters in November 2006.
