 What would become PA 332 between Newtown and Yardley was designated part of Legislative Route 252 in 1911. PA 332 was created in 1928 to run from PA 263 in Hatboro east to Ivyland with the road between Newtown and Yardley designated as part of PA 532. By 1940, PA 332 was extended to PA 113 in Newtown. The route was extended to Yardley by 1947, replacing PA 532. PA 332 was routed to bypass Newtown in 1991 when the eastern portion of the Newtown Bypass was completed.
