Project Overview

The Montana Department of Transportation (MDT) is proactively investing in safe, pedestrian-friendly infrastructure in Montana to reach its Vision Zero goal. River's Edge Trail Connector Project will provide a much-needed missing link in the River's Edge Trail system by constructing a pedestrian trail near the Missouri River in Great Falls along River Drive.

The River's Edge Trail Connector Project will move the River's Edge Trail from between Broadwater Bay and 1st Avenue to alongside the river. This project will replace the trail section that is highly confusing for users due to its route behind the police department and the water park. Moving the trail will improve safety for pedestrians and trail users, as the current section crosses busy streets and an active railway in two places. The proposed trail alignment along the edge of the river eliminates those crossings.

MDT is teaming up with the City of Great Falls, the River's Edge Trail Foundation, and TD&H Engineering to accomplish this important project.

The trail will cross the north entrance to Broadwater Bay parking and boat ramp before traversing through the park. At the north end of the open park area, it will follow the edge of River Drive along the Missouri River. From the railroad bridge, the pathway will divert west and hug the bank of the river for approximately 300 feet. From the riverbank, the trail will turn away from the river and enter the park, where it will link up with the existing trail at a "T" intersection just south of Central Avenue West. The proposed new trail will be 10-feet wide with five-inch thick concrete surfacing.

Design Options

During the design process, MDT will investigate shifting River Drive South away from the river south of the railroad bridge to minimize impacts to the river. In addition, this option could create more space between the trail and the road, increasing trail safety.

MDT will also be considering two design alternatives for the section of the trail that hugs the riverbank. A retaining wall or bridge will be needed to keep the trail away from the river.

Alternative One: Retaining Wall
This option includes constructing a portion of the trail as a causeway with a retaining wall under the railroad bridge. The retaining wall will be located next to the railroad bridge pier and slightly encroach into the river channel. Hydraulic modeling is being completed to determine if this option is feasible.

Alternative Two: Bridge
This option involves building a bridge along the riverbank under and around the railroad bridge pier. This option is being examined for feasibility around the bridge pier and along the riverbank. Portions of the bridge may be a cantilevered structure.

Engineer to English

Causeway: a trail, roadway, or railroad track located on the upper point of an embankment that crosses a body of water.

Cantilever: a rigid structural element that extends horizontally and is supported at only one end. A wall or other horizontal surface serves as its anchor, and it must be secured firmly. Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab.

Public Involvement

In addition to seeking general public comment on the project, MDT also seeks public comment on each specific design alternative. Those wishing to comment on the project should contact Aly Russell at alyr@strategies360.com or 406-223-5058.
