U.S. Route 122 (1935–1963)

U.S. Route 122 (US 122) was a United States Numbered Highway that was a spur of US 22. Located in the state of Pennsylvania, it existed from 1935 to 1963. At its greatest extent, the route ran from US 1 and Pennsylvania Route 472 (PA 472) in Oxford north to US 11 and PA 14 in Northumberland. Along the way, US 122 passed through Parkesburg, Honey Brook, Morgantown, Reading, Hamburg, Schuylkill Haven, Pottsville, Frackville, Ashland, Centralia, Mount Carmel, Shamokin, and Sunbury.

What would become US 122 between Reading and Northumberland was designated as part of US 120 in 1926. In 1927, PA 42 was designated onto what became US 122 between Oxford and Centralia, running concurrently with US 120 between Reading and Centralia. The same year, US 120 became concurrent with PA 45 between Ashland and Shamokin, PA 55 between Shamokin and Sunbury, and PA 14 between Sunbury and Northumberland. All the concurrent state routes except PA 14 were removed from US 120 in 1928, which split PA 42 into two sections; the southern section ran from Oxford to Reading. In 1935, US 122 was designated to run from US 1/PA 472 in Oxford north to US 11/US 111/PA 14 in Northumberland, replacing PA 42 between Oxford and Reading and US 120 between Reading and Northumberland. In the 1950s, the south end of US 122 was cut back to PA 23 in Morgantown, with PA 10 replacing the route between Oxford and Morgantown. US 122 was decommissioned in 1963 and was replaced with an extended PA 10 between Morgantown and Reading, PA 61 between Reading and Sunbury, and PA 147 (now PA 405) between Sunbury and Northumberland.
