Center Street, Lyndon, VermontMiller's Run Covered Bridge
The Miller's Run Covered Bridge, also called the Bradley Covered Bridge, carries Center Street over Millers Run in Lyndon Center, north of central Lyndon. It is a single-span queenpost truss bridge 56 feet long and 17.5 feet wide, with a 15-foot roadway and a cantilevered sidewalk on the east side. It is open to vehicles.
E. H. Stone built the bridge in 1878. It was the last of Vermont's 19th-century covered bridges to carry a numbered state highway, first Vermont Route 122 and later Route 122 Alternate. An overheight truck damaged its south portal in 1973. In 1995, after the state proposed removing it, townspeople pushed to keep it, and it was taken apart and rebuilt on a steel support structure, reusing the original trusses and adding a pedestrian walkway. It was listed on the National Register of Historic Places on June 13, 1977. Box trucks continue to strike it; in 2024 Lyndon's town administrator said it is hit about five times a year.
The queenpost truss uses two vertical posts joined by a horizontal beam. Since 1995 the wooden deck has rested on steel beams, with the original queenpost trusses kept.
The bridge is on Center Street in Lyndon Center and carries vehicle traffic. The sidewalk on the east side lets pedestrians cross separately.
