What to expect

At the Leland Creek site, travelers will experience one-way alternating traffic starting April 7, 2023, and continuing through early October. The speed limit is temporarily reduced for traveler and crew safety.

US 101 reopened to all traffic between Leland Cut Off Road and Leland Valley Road on Friday, Aug. 19. The road was closed for 19 days as crews replaced culverts at two unnamed tributaries to Leland Creek.

US 101 at Leland Creek is 33% passable to Chinook, steelhead, bull trout and coho salmon.
