Elk Run diverging diamond interchange opens to traffic
Access closures at 520th Street and 120th Street
ROCHESTER, Minn. – Motorists will now be able to use the Elk Run diverging diamond interchange and new Olmsted County Road 12 and Olmsted County Road 31, according to the Minnesota Department of Transportation. Map of new roads open to traffic.
Access from Highway 52 to 520th Street and 120th Street will close permanently on Wednesday, Sept. 4. Motorists can access 520th Street and 120th Street from the new interchange and frontage road system.
The Elk Run interchange’s innovative design brings one of the first diverging diamond interchanges (DDI) to Minnesota. With the DDI design, opposing lanes of traffic criss-cross at the ends of the interchange. Traffic signals, signs, pavement markings and concrete barriers guide motorists through the interchange.
The DDI design provides several benefits, including:
- Cost Effective: The DDI design is more cost effective to construct than the typical loop and ramp interchange design.
- High Capacity: The DDI design has the ability to accommodate high traffic volumes with improved safety.
- Pedestrians/Bicycle Access: The DDI design provides safe access for pedestrians and bicycles.
More information about the design, including an illustration and animations, can be found on the project website, www.dot.state.mn.us/elkrun/.
In addition to the interchange’s innovative design, three multi-lane roundabouts were constructed on the new county road system.
Multilane roundabouts are designated by signs and pavement markings to direct drivers into the appropriate lanes.

The Elk Run Interchange project reflects another phase of MnDOT’s overall effort to upgrade Highway 52 to a fully access-controlled freeway facility from Rochester to the Twin Cities.
The project included construction of the new interchange on Highway 52 in Pine Island, as well as access closures and a supporting frontage road system.
Construction began in 2011 on the $34.3 million project; Shafer Contracting Co, Inc. was the prime contractor.
