History
When Pennsylvania first legislated routes in 1911, present-day PA 282 was not given a route number. In 1928, PA 282 was designated onto its current alignment between PA 82 northwest of Glenmoore and US 30/PA 1 in Downingtown. Upon designation, the entire length of the route was paved. The route has remained on the same alignment since it was first designated.
