Olmsted County Approves $76.2 Million Highway 14 Interchange Project
Olmsted County commissioners approved a nearly $76.2 million contract for the construction of a U.S. Highway 14 interchange located at 60th Avenue Northwest. This project, spanning over two decades, aims to address safety concerns, enhance mobility, and stimulate economic development along the corridor.
"Although this project is primarily about safety, it will significantly drive economic development," stated Commissioner Gregg Wright, comparing it to the West Circle Drive development. He added that the interchange is expected to attract considerable economic activity, similar to what happened with Circle Drive.
Construction is scheduled to begin in the fall of this year, with a projected completion date of the end of 2028. Sleepy Eye, Minnesota-based Mathiowetz Construction Co. was awarded the contract, submitting the lowest bid among eight proposals received. The lowest three bids were within 8% of each other, demonstrating a competitive bidding process.
Current roadways will remain open throughout the upcoming winter, but 60th Avenue closures are anticipated once construction commences in earnest. Ben Johnson, Olmsted County Public Works Director, assured that Highway 14 will remain open during most of the construction, with temporary closures and detours expected.
The interchange will feature four bridge structures, with the new structure located approximately 300 feet west of the existing 60th Avenue intersection. Westbound Highway 14 on- and off-ramps will cross the railroad line, and new roundabouts will be installed for north and south traffic. A new flyover bridge at Seventh Street Northwest will also be constructed, improving traffic flow while ensuring safety.
When combined with planning, engineering, land acquisition, and other costs, the project is estimated to cost $93 million, making it the largest locally led project in Olmsted County's history. A $60 million Minnesota Corridors of Commerce grant, along with additional state and federal funds, will cover a significant portion of the expenses.
"Traffic has increased with regional growth along the corridor, which presents safety risks," said Nancy Daubenberger, Minnesota Department of Transportation Commissioner, emphasizing the need for the new interchange and overpass. She noted that these infrastructure improvements are intended to support anticipated future growth between Byron and Rochester.
According to Olmsted County, approximately 30,000 vehicles travel daily on Highway 14 between Rochester and Byron, and 3,000 daily trips occur at the 60th Avenue intersection with Highway 14.
