The long-anticipated overhaul of John Nolen Drive is underway, marking the start of a multi-phase reconstruction project aimed at revitalizing the critical corridor between West Washington Avenue and Blair Street.

The work will widen the roadway, rebuild aging infrastructure, including six crumbling bridges, and improve safety for motorists, bicyclists, and pedestrians. Upgrades include underground utilities, stormwater systems, and new sidewalks and bike lanes along the causeway between Lake Mendota and Monona Bay.

This is the largest John Nolen Drive renovation in decades, fixing persistent issues with deteriorating pavement, structures, and inadequate bike and pedestrian access. Planners say the current design is outdated for the volume of traffic between downtown Madison and the Isthmus.

This fall, crews will begin site preparation, utility relocation, and grading, with major pavement reconstruction set for next year. Project leaders aim to phase lane closures and detours to keep traffic moving and reduce effects on nearby neighborhoods and businesses.

Funding comes from local and federal sources, including a federal grant for the six bridge replacements. The investment supports Madison’s transportation goals, including improved bicycle connectivity and safer crossings.

City engineers will update the public throughout construction, sharing closure and traffic details as work advances.
