More than 100 covered bridges have been built in Massachusetts since Timothy Palmer’s 1792 open timber truss bridge at Amesbury was roofed in 1810. In the 20th century, Massachusetts experienced a modest revival of timber covered bridge construction. A handful of “Massachusetts modern” covered bridges were built in the 1950s, 1960s, and 1970s as replacements for historic wooden bridges too dilapidated to be saved. Today, a handful of both the old and the new covered bridges of Massachusetts still stand, and delight visitors, photographers, and people who love traditional structures.
