About the project

MnDOT - District 6 (Rochester/Owatonna/Winona)
State Project Number: 5508-84

This project, completed with a single design-build contract includes improvements:

  • Diamond interchange at County Road 112/ 12 (S)
  • Overpass at County Road 12 (N)
  • New mainline bridges over Lake Shady
  • Frontage road construction to facilitate access to local roads
  • Access control measures to improve safety

The proposed project provides safer and more efficient traffic operations on Hwy 52 and the adjoining county/local road system.

Location

  • Hwy 52 segment located in Olmsted County
  • Starts near junction of 85th Street and continues northerly to the 59th Avenue intersection in Oronoco
  • Hwy 52 between Rochester and the Twin Cities is classified as a high-priority interregional corridor

Cost

  • $37 million

Background

  • This segment of Hwy 52 features several at-grade intersections.
  • Heavy traffic volumes and high speeds make it difficult for traffic to safely access the highway from local cross streets and public roads.
  • A December, 2000 Road Safety Audit revealed that the County Road 12(N) intersection in Oronoco had an accident rate twice as high as the statewide average for similar intersections.
  • Additionally, the existing northbound Hwy 52 bridges over Lake Shady qualify for replacement based on age, condition, bridge sufficiency ratings, substandard hydraulic capacity and substandard width.
