Wis 310 was designated in the early 1980s when I-43 was constructed, providing a direct state trunk highway connection between Two Rivers and the freeway. It generally follows the former route of County D. Wis 310 was designated as a connector route in Wisconsin's Corridors 2030 plan, which identifies it as an important regional corridor and gives it priority for improvements.
The City of Two Rivers passed a resolution asking the Wisconsin Department of Transportation (WisDOT) to make Wis 310 four lanes so it can have a high quality roadway connect with the city. WisDOT responded to Two Rivers by making Wis 310 a high quality roadway by improving the existing roadway. An improvement project in 2008 reconstructed most of Wis 310 which included two new traffic signals, a new West Twin River bridge, and three new roundabouts. Currently there are no other official plans to make Wis 310 four lanes.
