Alternating Lane Closures and Traffic Shifts on US20 Westbound Start on Wednesday

Beginning on Wednesday, Jan. 31, and in preparation for construction for the Southwest Arterial/US52 and US Highway 20 interchange bridges, the westbound two-lane traffic on US20 will shift and detour onto the newly constructed westbound ramp for the Southwest Arterial interchange at Seippel Road.  The transition will require alternating westbound lane closures between 9 a.m. and 2 p.m. on Wednesday, Jan. 31.

US20 westbound traffic will remain detoured onto the two-lane westbound ramp until construction of the Southwest Arterial/US52 and US20 interchange is completed in the summer of 2019. The speed limit through the construction zone detour will be reduced and posted at 45 MPH.
