 Due to the excavation of a large trench across the Parks Highway at Mile 237, near the entrance to the Denali Park Road, travelers will experience a detour beginning at 12:01 a.m. on Monday, October 4 until 6:00 p.m. Friday, October 8. The trench will accommodate piping for the new wastewater treatment facility for the park’s entrance area, which is under construction west of the highway.

Traffic will be diverted around the trench via a 100 yard temporary bypass lane constructed on the west side of the road. Flagger personnel will control traffic 24 hours a day until the project is complete. Minimal traffic delays are expected.

Additional park information is available at or by calling (907) 683-2294 between the hours of 8:00 a.m. – 4:30 p.m.
