Denny Way Bus Upgrades Planned This Summer Include Permanent I-5 Ramp Reroute

Seattle Mayor Katie Wilson announced plans to speed up Route 8 service on Denny Way with a new half-mile eastbound bus lane and permanent I-5 ramp reroute, set to take effect in August 2026. The changes include closing a slip lane at Stewart Street and redirecting southbound I-5 traffic through Boren and Howell Avenues. Route 8 frequency will also increase from every 15 minutes to every 12 minutes starting August 29, funded by the 2020 Seattle Transit Measure.
