Construction complete, no more detour.
Attention TCMSA members: The Pasco-Kahlotus Highway is closed near the Highway 12 interchange for construction of a new sewer, water & other utility crossing, and is expected to be closed until early July. There is currently a detour along Commercial Ave to the south. Please see the map below. The detour route has signs on it. Also watch your speed on this route, it’s 35 MPH not 55 MPH like the highway. We will let you know if the route changes or if anything else comes up.
