Diffley Road and School Access

Diffley Road (CSAH 30) provides a vital connection for commuters and residents to the City of Eagan, including access to Eagan High School. Improvements to Diffley Road were needed to ensure the safety of students and other travelers. In late 2019, a student crossing the four-lane divided roadway was struck and killed at an uncontrolled, unmarked intersection. This incident propelled the county, city, and ISD 196 to rapidly push forward a school area safety improvements study.

Bolton & Menk led the study, gathering community input and collaborating on short- and long-term improvements. Using the momentum from the recent study, we worked with stakeholders to implement a lane reduction of Diffley Road east of Lexington Avenue, single-lane roundabouts at Daniel Drive and Braddock Trail, a new access road from Diffley Road to Dakota Hills Middle School/Eagan High School’s south parking lot, a school parking lot reconfiguration and expansion, and improvements to parking lot access along Braddock Trail.

These much-needed improvements will help Dakota County realize their vision of a safer Diffley Road and school area.
