Union Covered Bridge State Historic Site

Union Covered Bridge State Historic Site

Missouri (Monroe County)

Union Covered Bridge State Historic Site preserves one of only four remaining covered bridges in Missouri — and the only one built using the Burr arch truss design. Spanning the Elk Fork of the Salt River in rural Monroe County, this 1871 bridge stands as a quiet testament to 19th-century craftsmanship and the ingenuity of early American engineering.

At just 1.24 acres, this is an intimate historic site rather than a sprawling park, but what it lacks in size it more than makes up for in character. The single-lane wooden bridge stretches 125 feet across the river, its weathered timbers framing views of the surrounding countryside. It’s the kind of place that rewards a slow visit — bring a camera and take your time exploring the structure up close.

The site offers a short walking area around the bridge with interpretive signage explaining the bridge’s construction and history. It served daily traffic for over a century before being retired and preserved. Picnicking near the riverbank is a popular activity, and the Elk Fork draws occasional anglers.

There’s no camping on-site, so plan this as a day stop — it pairs well with a broader driving tour of northeast Missouri’s small towns and back roads. Spring and fall deliver the best conditions, with wildflowers framing the bridge in April and foliage creating a photographer’s dream in October.

Union Covered Bridge is a small detour with outsized charm — a piece of Missouri history you can walk right through.
