The Green River Trail is closed at Fort Dent through October 2026 as part of the levee reconstruction project. Although a temporary trail has been built around the construction zone, do not use it. The surface is very slow, loose shredded bark, and the trail is not guaranteed to always be open. The detour is to ride on the sidewalk along Interurban Ave S or in the roadway.

At the north, the detour begins at the casino, at S 141st/58th Ave S. Continue on the sidewalk instead of turning east on the GRT.
At the south, the detour begins at Fort Dent Way. Where the GRT and Interurban Trails meet Fort Dent Way, turn left toward Interurban Ave S, then right on the sidewalk along Interurban.
If your route uses the Lake to Sound Trail (formerly Black River Trail), it is still accessible from the GRT. At the casino, follow the GRT.
The following routes are affected. The detour has not been incorporated into the RwGPS files. The detour is about 0.2 km shorter than staying on the GRT; rides that use the detour in both directions will be about 0.4 km short. Ensure that you ride some extra distance if necessary to meet the route’s official distance.
