context_page_description: U.S. Route 422 is a 271-mile long spur route of US 22 split into two segments in the U.S. states of Ohio and Pennsylvania. The western segment of US 422 begins in downtown Cleveland and ends at Ebensburg, Pennsylvania. The eastern segment, located entirely within Pennsylvania, begins in Hershey and ends at King of Prussia, PA, near Philadelphia. U.S. Route 422 Business is the offshoot road into each of 4 towns along the way.
  The segmented nature of US 422 violates AASHTO numbering, as two separate roadways traditionally do not carry the same route number. However, the two sections of US 422 are connected by US 22 and US 322, allowing the two halves of US 422 to carry the same designation.
  In downtown Cleveland, the western terminus of the western segment of US 422 is at US 6, US 20, US 42, and State Route 3 in Cleveland's Public Square. In Hershey, Pennsylvania, the eastern segment of US 422 begins at an interchange with US 322 and Pennsylvania Route 39. US 422 is named the Benjamin Franklin Highway in Pennsylvania.
  Originally, US 422 was routed along existing roads, but much of the route now runs along purpose-built alignments.
