The purpose of the study was to develop preliminary concept designs for intersection improvements to Hwy 36 at the intersections of Hwy 120 (Century Ave) and Hwy 35 (Hadley Ave), located just west of I-694. The study included evaluation of alternative intersection designs, interchange designs and concept level layouts for selected concepts.

The preliminary concepts identified recommended access control. They also recommend supporting road connections in an attempt to conform to access spacing guidelines, public and private utility issues, storm water management options, wetland impacts and identification of other critical issues.

Officials of the State, MnDOT, Mn DNR, City of Oakdale and City of North St. Paul, Ramsey and Washington Counties, and local businesses and residents worked in coordination throughout the study.
