Marquette Trail Underpass

Four students from the College of Engineering's Department of Civil and Environmental Engineering completed a study for a possible underpass for pedestrians and cyclists on behalf of the City of Marquette and the Driftless Area Wetlands Centre. They were tasked with figuring costs and best options to connect an existing trail to three other points in the community: the Driftless Area Wetlands Centre, Bloody Run Campground, and Timber Ridge Subdivision. The students identified three alternatives, highlighting the pros and cons of each.

In order to provide a safe alternative route for cyclists and pedestrians from downtown Marquette to the Driftless Area Wetlands Centre, a campground, and a nearby subdivision, the key challenge was to identify the best way to cross U.S. Highway 18. Other impacts to the team's design choices were the nearby railroad network and protected wetlands.

The students researched three alternatives for creating a safe crossing of the highway. These included utilizing an existing box culvert, constructing a new box culvert, and constructing a pedestrian surface crossing. The team created plans and costs for all three options.
