(North Platte, Neb.) —Weather permitting, construction will begin April 7 on State Highway 21 (N-21) in Cozad at reference post 13.83, according to the Nebraska Department of Transportation.

Lobato Construction, LLC, of Brighton, Colo., is the contractor for this project. Work includes repair and resurfacing of the N-21 viaduct over the Union Pacific Railroad, including new street lighting and sidewalk. Traffic will be reduced to one lane controlled by temporary traffic signals. A 10-foot width restriction will be in place. A pedestrian shuttle will be operated while the sidewalk is closed. Anticipated completion is fall 2025.

The purpose of this project is to preserve the transportation asset, improve the reliability of the transportation system and perpetuate the mobility of the traveling public.

Motorists should expect reduced speeds and lane reductions within the work zones and are reminded to drive cautiously through highway construction zones.
