Olympic Peninsula 2025 construction

Welcome to our online open house!

Travelers headed to Washington’s Pacific Ocean beaches or around the Olympic Peninsula will need to add extra travel time.

This year, our construction and maintenance crews will make improvements to sections of US 101, US 12 and State Routes 8, 104, 112 and116 and in Grays Harbor, Mason, Jefferson and Clallam counties. People will travel through multiple work zones that may have reduced speeds and shifted lanes with temporary traffic signals.

To help plan and navigate work zones around the Olympic Peninsula, we invite you to explore this online open house. Construction work zones are sorted by county.

Along US 101 west of Olympic National Park through Port Angeles to points beyond, travelers will encounter work zones for bridge work and fish barrier removal.

On SR 104 near the Hood Canal Bridge, crews are finishing a new roundabout for safety improvements. Further north on SR 116, crew will replace an outdated culvert that will require a detour. Some of this work will cause minor slowdowns. There are a few projects that will require temporary road closures, detours, or extended wait times.

Work zone safety

The people in work zones are spouses, parents, children, siblings and friends. They all deserve to go home safe at the end of their shift. Please pay attention in work zones to help save lives. Slow down. Be kind. Pay attention. Stay calm. Plan ahead.
