The Southbound TH 52 Cannon Falls to Zumbrota Design-Build project encompasses a comprehensive transformation of the Highway 52 corridor in Minnesota, spanning from Highway 60 east near Zumbrota to Goodhue County Road 24 near Cannon Falls. The project covers approximately 20 miles and was completed over two years with a budget of $80 million. The project
included replacement of Highway 52 Southbound’s mainline pavement while enhancing safety and access management.
The project transitions the corridor to a freeway design with no direct access to the highway, achieved through the construction of a new interchange at the existing intersection of Hwy 52 and Hwy 57. The challenge of maintaining traffic on this heavily traveled corridor required the phased construction of the grade-separated interchange. The project also includes 13 miles of
highway reconstruction with new concrete pavement, two new interchange bridges, a bridge over the Zumbro River, an overpass bridge at the junction of TH 60W and TH 52, and additional infrastructure such as box culverts at Belle Creek and Butler Creek.
Notably, the initiative extends Goodhue County Road 14 by 1.5 miles from 57th Street to County Road 24. By addressing both pavement replacement and access management, the Southbound TH 52 project contributes to the overall enhancement of transportation efficiency, safety, and infrastructure resilience in the region.
