MnDOT initiated the ROC 52 Design-Build project to improve safety, reduce congestion, and provide a safer and more connected frontage road system. Working as a quality oversight consultant on behalf of MnDOT, SRF reviewed designs and plans to ensure that they met the criteria in the RFP. SRF also provided expertise in structural engineering and drainage.
As part of the MnDOT Oversight Team, SRF frequently met with the design-build team to develop solutions to design and construction challenges. The MnDOT Oversight Team staff also visited the construction site to meet with inspectors and construction crews when problems arose in the field.
The project expanded Highway 52 from four to six lanes from Highway 63 to 75th Street NW and included new and reconstructed interchanges, two new overpasses, new and reconstructed frontage roads, and noise walls.
ROC 52 was MnDOT’s first and at that time largest “design-build, best value” highway project.
