The current condition of the roadway and bridge is highly deteriorated. The addition of left-turn lanes in the medians on WIS 144 will help create a safer condition for vehicles turning left onto the ramps. Parallel ramps will allow traffic to safely exit and enter on to US 41.

Ramp gates will be added to the on ramps for controlling traffic entering the freeway during an incident.


March through late fall 2014

Traffic impacts/Detours

  • WIS 144 traffic will be able to cross US 41 either using the existing or new bridge.
