The Roman Bridge is located within the municipality of Muccia, near the road connecting the town of Pieve Torina to the hamlet of Colfiorito in Foligno. It is indicated by a sign that leads along a dirt path.

The bridge was once crossed by the Val S. Angelo road, a branch of the ancient Via Flaminia, whose route was later diverted to a larger bridge. The name of the valley derives from the Lombard cult of Saint Michael the Archangel, to whom the nearby hermitage, situated on a hill overlooking the bridge and now also known as the Hermitage of the Saints, was dedicated.

The bridge’s structure, featuring a round arch, is notable for being built almost entirely of sponga stone, a type of light and porous travertine quarried from the picturesque gorges of the nearby S. Angelo stream.

Interestingly, at the entrance of the valley, a Bronze Age necropolis was discovered; its artifacts are now preserved in the National Archaeological Museum of Ancona.
