WIS 19 (WIS 78 to US 12) - Dane County
The Wisconsin Department of Transportation (WisDOT) is in the process of developing plans for a proposed improvement project on WIS 19 in Dane County. The project begins at the WIS 78 intersection and extends easterly for 9.6 miles to the US 12 intersection.
The purpose of the project is to improve corridor safety, address drainage concerns, widen shoulders, and improve pavement condition.
The proposed improvement includes:
- Upgrading select horizontal and vertical curves.
- Replacing two bridge structures.
- Replacing existing guardrail.
- Protecting existing roadside hazards.
- Rehabilitating select roadway culvert pipes.
- Replacing existing signing and pavement markings.
- Widening shoulders from 0-2’ to 6’ (3’ paved) west of County K.
- Widening shoulders from 0-2’ to 6’ (5’ paved) east of County K.
- Installation of pedestrian crossing at Indian Lake Park
This project follows the shoulder repair project that was constructed in the summer of 2017 that addressed the immediate needs of the roadway.
