The Bradley Covered Bridge, also known as the Miller’s Run Covered Bridge, is a historic covered bridge, carrying Center Street over Miller Run, a tributary of the Passumpsic River, in Lyndon, Vermont. Built in 1878, it is the last of Vermont’s many 19th-century covered bridges to carry a numbered state highway (first Vermont Route 122 then later Vermont Route 122 Alternate). The bridge was listed on the National Register of Historic Places in 1977.
