Highway 370 is the main east–west road in Sarpy County, which serves the southern Omaha suburbs.

About a mile later is Werner Park on the north, home of the Omaha Storm Chasers, the Kansas City Royals' Triple-A affiliate in the International League.

It passes through the southern portion of Papillion and at about 48th Street, enters Bellevue; after two miles (3.2 km), it ends at U.S. Route 75, the Kennedy Expressway, and then becomes Harlan Drive.

Prior to 2014, the highway continued east along the remainder of Harlan Drive, turned south at its intersection with Galvin Road, then turned east as Mission Avenue through Olde Towne Bellevue.

The Iowa highway was turned over to Mills County upon completion of the U.S. Route 34 bridge six miles (10 km) southeast of Bellevue, and the Nebraska state-maintained length was shortened to its present terminus.
