PA 842 eastern terminus at US 322 Bus. in West Chester
Miner Street in West Chester, which comprises part of PA 842, was laid out in 1831 as part of an expansion of West Chester built by William Everhart. The street was named for Charles Miner, a West Chester resident.[5] When Pennsylvania first legislated routes in 1911, what would become PA 842 was not legislated as part of a route.[6] PA 842 was first designated by 1928 to run from PA 82 in Unionville east to US 122/PA 5/PA 62 (now US 322 Bus.) in West Chester, following its current alignment.[7] In 1937, PA 842 was extended west from Unionville to its current western terminus at PA 841.[8][9] PA 842 has remained on the same alignment since.[3]
