Starting Tuesday, March 12, US 101 travelers near Forks will see around-the-clock single-lane alternating traffic. The work zone is located at the Jefferson-Clallam county line.

What to expect

Contractor crews will install temporary traffic signals. The traffic signals will alternate traffic through the May Creek work zone.

Red light, green light

The temporary traffic signals have red, yellow, and green lights. They work just like permanent traffic signals. Travelers will see one-way alternating traffic through the fall of 2026.

The speed limit on US 101 is reduced to 25 mph from 55 mph between mileposts 184 and 185.

The temporary changes help keep people moving while crews begin excavating the entire highway for a fish barrier removal project. Crews will build a 175-foot-long girder bridge to replace an outdated culvert under the highway.

Whenever near work zones please:

• Slow down – drive the posted speeds and observe the signals, they’re there for safety.

• Be kind – our workers are out there helping to keep everyone safe and improve the roadways.

• Pay attention – both to workers and signals directing traffic.

• Stay Calm – expect delays, leave early or take alternate routes if possible; no meeting or appointment is worth risking someone’s life.
