History
In 1911, what would become PA 21 was designated as part of Legislative Route 256 between the West Virginia border and Rogersville, Legislative Route 111 between Rogersville and Waynesburg, and Legislative Route 112 between Waynesburg and Uniontown.[7] PA 21 was designated in 1927 to run from the West Virginia border east to US 40 in Uniontown. The route followed its current alignment to west of Carmichaels, where it headed east by way of Carmichaels and New Salem to Uniontown. The alignment utilized a ferry across the Monongahela River.[8][9] By the time of its inception, PA 21 existed as a paved road between Wind Ridge and PA 121 east of Waynesburg, in the Carmichaels area, and from south of Republic to Uniontown.[9] The remainder of PA 21 was paved by 1940.[10] By 1950, PA 21 was rerouted to follow PA 88 between Carmichaels and Paisley, where it turned east and crossed the Monongahela River at Masontown and followed its current alignment to Uniontown.[11] Bypasses of Carmichaels and Masontown were built by 1960. Also by this time, PA 21 was widened into a divided highway near the PA 88 intersection in Paisley,[12] By 1970, a portion of PA 21 east of Waynesburg was converted to a divided highway.[13] A new, four-lane Masontown Bridge over the Monongahela River was completed in 2015. It replaced the two-lane bridge built in 1925.[14]
