Historic Bridge Adoption

Musselshell River Bridge on Parrott Creek Road

The Montana Department of Transportation (MDT) plans to replace the Musselshell River Bridge at Reference Post 0.4 on Parrott Creek Road. Historically known as the Gage Bridge, the structure was built in 1916 and was one of the first constructed by a Montana county using plans developed by the old Montana State Highway Commission. The MDT plans to replace the bridge in 2016. The single-span steel bridge is 122.5 feet in length and 18 feet wide. It is estimated to weigh approximately 59 tons with the timber deck and 37 tons without the deck. The bridge is eligible for listing in the National Register of Historic Places.

Anyone interested in adopting the old bridge would be required to obtain the necessary permits, provide MDT with plans on how the bridge would be moved, and the intended use of the structure. For further information, please contact at 406-444-6260.

There are so many wonderful ways to use old historic bridges.

The Montana Department of Transportation is dedicated to preserving and interpreting sites across the state that document Montana’s exciting history. Old bridges can be found throughout the Big Sky Country, providing not only a link across rivers, but also a connection between the people who built them and those who came after.

Jon Axline’s book, Conveniences Sorely Needed: Montana’s Historic Highway Bridges 1860-1956, explores the forces that built Montana’s historic bridges and the structures’ importance to the communities they served.

Program Details

As Montana updates its transportation system, new bridges replace the old. The bridges they replace still have the structural capacity to carry bicycle and pedestrian traffic and some cars. MDT usually puts the old bridges up for adoption.

Adoptee’s may be eligible for a "Historic Preservation Grant" from MDT up to the estimated demolution costs.
