What to expect

Two sections of US 101 between Gardiner and Sequim are using two-lane bypass roads. Both have reduced speed limits. Bypass roads keep people moving around the work zones.  Both will be used through summer 2024.

Bypass road locations

  • Near West Sequim Bay Road at milepost 268.5 - Discovery Creek 
  • Near Deerhawk Drive at milepost 271.9 - Chicken Coop Creek

Travelers will also see daytime shoulder closures and occasional night one-lane alternating traffic. 

People walking or riding bicycles on US 101 may see a detour via the Olympic Discovery Trail. See more in "Maps and Drawings."

This project will replace six existing culverts beneath US 101 between milepost 267 and 278.
