Martin Covered Bridge Park is a 120-acre town park. The park includes a one mile walking trail, a covered bridge , and great fishing spots. There is a parking lot off of Route 2. The bridge was built about 1890 by Herman F. Townsend, a prominent local bridgewright. It is one of the few surviving 19th century bridges in the state that was originally built on a private road, and is Marshfield's only surviving historic covered bridge. It has been restored and is now a pedestrian-only bridge to access the park.
