next project

Highway 407 East Extension Phase 2

Reconstruction of WIS 42/57 facilitated essential roadway improvements, while bringing Door County’s first roundabouts.

As an important corridor in Door County, WIS 42/57 required reconstruction to increase the level of service for residents and visitors to the County. The design for this important 1-mile segment brought roadway improvements and two new roundabouts at Michigan Street and Egg Harbor Road.

Roundabouts provided a solution unique to the region that has kept traffic moving safely while minimizing environmental impacts. Improved operations are now allowing travelers, the local economy and the region to keep moving forward.
