Overhauling a Town Road to Serve a New High School


A new high school was set to open in the City of Sartell, Minnesota. The rural road that serviced the high school was too narrow and could not adequately provide the safety and efficiency for drivers and pedestrians that the new high school would require.


The City of Sartell partnered with SEH to redesign Pinecone Road to better service the new high school. The existing roadway was inadequate to serve the additional 2,500 trips the high school would add. To address the inadequate road, the project team expanded it from a 24-foot, two-lane rural to a 45 foot wide urban section with off-road bike lanes. Additionally, the project included two roundabouts and a three-quarter intersection, which helped to reduce crash probability by 44 percent. With the roundabout at 35th street, left turns into the school driveway occur against the slower moving southbound traffic, further reducing crash potential.

The project also featured radar feedback signage to let drivers know their speed through the heavily travelled corridor, as well as wayfinding signage throughout the corridor and along the bike path.

SEH also collaborated with the School District to provide stormwater treatment for both the roadway and the development of the high school into a single, larger infiltration basin, rather than into multiple ponds.

To keep the project on track, a significant public outreach campaign was put into place. SEH worked closely with the City and the School District to engage and inform the public at the onset of the project. The public engagement efforts were key in delivering this project and addressing public concerns about safety surrounding the new school building. These efforts included multiple public information meetings as well as in-home meetings with citizens. SEH prepared renderings that in conjunction with informational videos were shared via the School and City’s social media accounts, reaching tens of thousands of stakeholders.
