SR 3 - Chico Creek - Remove Fish Barriers

Project overview

This project is part of WSDOT's ongoing Fish Passage Barrier Removal Program where construction projects remove barriers to fish. The Chico Way/State Route 3 interchange has several barriers to fish under both directions of SR 3 and under the highway's southbound on- and off-ramps. This construction project will build replicated natural streambeds for Chico Creek and a tributary to Chico Creek.

What to expect

Travelers using the Chico Way/SR 3 interchange can expect regular night ramp closures. The Chico Way on-ramp to southbound SR 3 closes at 8 p.m. to 6 a.m. each following day. Northbound SR 3 exit to Chico Way closes at 7 p.m. to 5 a.m. each following day. During weekend mornings, ramps reopen as late at 10 a.m. SR 3 single lane closures begin as early as 7 p.m.

Starting as early as Dec. 1, a temporary regulatory speed limit reduction from 60 mph to 45 mph on both directions of State Route 3 will be in place from milepost 40.71 to milepost 41.30 near Chico Way Northwest. The 45 mph speed limit will be enforceable as soon as signs are installed. The temporary speed limit reduction will remain in effect until the end of the project.  Once major construction is complete, WSDOT anticipates raising the speed limit back to its pre-construction 60 mph limit. 

WSDOT will keep people moving during the entire project. There is construction on both directions of SR 3 approaching the interchange. All lanes will remain open. Revised roadway routes of the southbound SR 3 exit to Chico Way and Chico Way on-ramp to southbound SR 3. Long-term closure of the Chico Way on-ramp to southbound SR 3. WSDOT will announce the closure when scheduled.
