District 6 Overview
Enhancing Financial Effectiveness
MnDOT is focused on stretching tax payer dollars while continuing to deliver effective and highly valued products, services and programs. Today we are using technology, partnerships, performance-based design, contracting methods, etc. to reduce costs, save time and limit impacts to travelers, shippers and businesses in order to deliver efficient and reliable multimodal transportation. A strategic priority, financial effectiveness is demonstrated by the following programs, among others, at MnDOT District 6.
Safety and Mobility (Hwy 52/Goodhue County Road 9)
- District staff, Central Office staff and Goodhue County officials had for the past several years been studying safety improvement strategies for the intersection of Hwy 52 and Goodhue County Road 9, where 96 crashes were recorded from 2000 to 2014.
- Eleven of the crashes occurred on the far side of the intersection, and resulted in serious injury or fatality.
- In spring 2013, Goodhue County applied for funding construction of a full diamond interchange through the MnDOT Corridor Investment Management Strategy (CIMS) program.
- Goodhue County was awarded a portion of the CIMS funds, but not enough to construct a diamond interchange.
- As a solution, MnDOT and Goodhue County partnered to look at other interchange designs that would provide a high return on investment, while meeting the goal to improve safety and mobility.
- Some key design needs were:
- A safe geometric design that would allow phasing a “full interchange” in the future.
- A grade separated intersection.
- Access from Hwy 52 to CR 9.
- Minimal construction impacts to Hwy 52 traffic, to farmland and the environment.
- The quadrant interchange was the concept design developed to meet those goals as well as reducing both farmland and wetland impacts by almost half and allowing for future expansion to a full interchange as traffic levels or safety needs dictate.
- This revised interchange design set the stage for future low-cost safety improvements and access management within the corridor.
- Construction-cost scoping estimate of the diamond interchange was $12 million, whereas construction-cost scoping estimate of the quadrant interchange was $8 million.
- Notably, the Hwy 52 and County Road 9 work was recently awarded as a Design-Build project at a cost of approximately $6.7 million, providing additional significant cost savings.
- Construction is set to begin in April 2014 and scheduled to be completed in November 2014.
