US 10 expansion project - purpose

Providing a safe and efficient highway system is an important part in meeting the needs of continued economic growth for central Wisconsin.

In its current two-lane capacity, US 10 is unable to provide safe and efficient travel as described in the Corridors 2020 transportation plan. The existing highway is routed through five communities, which increases conflict points between local and through traffic. Traffic volumes on US 10 are also expected to increase, which will further reduce the function of this highway.

US 10 will be constructed as a four-lane, 65 mph highway between Marshfield and Stevens Point. Controlled access on US 10 will increase safety and provide improved traffic flow. The highway between WIS 13 and Wood County N will have limited access at intersections located at approximately one mile spacing.

Access to new US 10 between Wood County N and I-39 will be restricted to interchanges located at WIS 34 south, WIS 34 north and I-39. An interchange will also be located at WIS 13/Wood County A near Marshfield.

The new I-39 and US 10 west interchange will be designed with free flow access, which will allow for high-speed ramp movements between the two highways. This interchange will be located near the current Portage County X interchange, which will require the removal of local access to I-39 at this location. Local access will be provided approximately two miles south at the newly constructed Casimir Road interchange.

Upon completion of construction of the new roadway, portions of existing US 10 will transfer to the jurisdiction of county and local units of government. These changes will take effect as the associated US 10 project is completed. These jurisdictional transfers are part of numerous state highway system changes associated with the US 10 project.
