Year: 2023

In 2017, Washington County and their partners embarked on a program to identify solutions to address necessary safety and capacity improvements at the Highway 36 and Manning Avenue at-grade intersection near Stillwater, Minnesota. Following the study, a new interchange was selected after an extensive alternatives evaluation process, coordination with numerous agencies, and comprehensive public outreach. The new interchange, opened to traffic in July 2022, yielded immediate and sustained benefits that will improve safety, capacity, and operations for all users and features a grade-separated crossing for pedestrians, bicyclists, and snowmobilers. Ancillary benefits include enhanced water quality and access for future development, including a planned commercial development and a new hospital campus. Additionally, the interchange was developed such that it does not preclude future improvements that are currently being studied at Highway 36 and Lake Elmo Avenue (County State Aid Highway 17) one mile to the west.
