The city is making repairs to the Duwamish Trail this week. From SDOT:
Repairs are underway on the Duwamish Trail in West Seattle. The asphalt trail has been heavily damaged in places by tree roots and needs to be repaired for bicyclist and pedestrian safety. SDOT crews are grinding off the old asphalt, trimming trees, cutting roots, and placing new asphalt this week, weather permitting, from 8 a.m. to 5 p.m. each day. The crews are assisting pedestrians and bicyclists around the work area. Due to weather conditions, the trail is muddy in the work area. Bicyclists may need to dismount and walk their bikes in places.
Funding for this project is provided by the Bridging the Gap transportation initiative approved by Seattle voters.
