The 1849 Quinlan's Covered Bridge, also called the Lower Covered Bridge, and Sherman Covered Bridge, is a wooden covered bridge that crosses Lewis Creek in Charlotte, Chittenden County, Vermont, and is one of nine 19th-century Burr arch covered bridges in the state.

Quinlan's Covered Bridge is a single-span multi-Kingpost & Burr arch truss, 86 feet long and 16.5 feet, with a roadway width of 13.5 feet. Each truss has, in addition to diagonal braces and vertical posts, a pair of timber arches bolted to it. It has a gabled roof, and its exterior is clad in vertical board siding, which extends around to the inside of the portals. It rests on stone abutments faced in concrete.

The builder is unknown, but most likely the same builder as the Sequin Covered Bridge upstream. The name "Lower Bridge" was because it is downstream of the Sequin (or "Upper") bridge. This is common in Vermont where multiple bridges cross the same body of water in the same town. The name "Quinlan" is attributed to the family of the same name that held land in the area. The name "Sherman" comes from the owner of a sawmill that was located adjacent to the bridge site.

In 1949 or 1950 steel beams were installed under the deck to strengthen it. The bridge underwent reconstruction in 2013.

Of the over 500 covered bridges that were built in the state of Vermont, as of 2019, only 104 remain.

Length of largest span: 80.1 ft.
Total length: 87.9 ft.
Deck width: 12.8 ft.
Vertical clearance above deck: 9.0 ft.
