BODY
Action Requested:
The Northfield City Council discusses the TH 246 and Jefferson Parkway Roundabout Options.
Summary Report:
The adopted 2019-2023 Capital Improvement Projects (CIP) includes the TH 246 and Jefferson Parkway Project. The City of Northfield performed an Intersection Control Evaluation (ICE) on the TH 246 and Jefferson Parkway intersection in 2016.

The City received $483,480 from MnDOT's Local Partnership Program (LPP) to be used on this project. These funds are appropriated for the 2020 fiscal year. In addition, the City of Northfield received $900,000 from MnDOT's Local Road Improvement Program (LRIP) appropriated for this project.
