Grand Trunk Trestle Doors Open St. Marys

Grand Trunk Trestle

Built as a Grand Trunk Railway viaduct over the Thames River, this trestle was used by trains until 1989. In the mid-1990s, the Town of St. Marys purchased it and created a volunteer committee to convert it into the Grand Trunk Trail, an integral part of the local trail system. In 1999, the Grand Trunk Trestle officially opened to pedestrians.
