and hit Saylorsburg via the Sullivan Trail. It then took Hamilton S to Sciota, then US 209 BUS and US 209 to the New York line at Milford. That year, PA 90 was designated from Stroudsburg to the New York-Pennsylvania border. From the 1920s to the 1940s, the designation between Stockertown and Stroudsburg had no signed traffic route. In 1928, several spurs were commissioned. For PA 90, the following spurs were assigned in The Poconos region: PA 190, PA 290, PA 390, PA 490, PA 590, and PA 690. In 1928, For PA 12, the following spurs were assigned in The Poconos and Lehigh Valley regions: PA 212, PA 312, PA 412, PA 512, PA 612, and PA 712. Later that year, concurrencies with national highways were removed, truncating PA 12 to terminate at Center Valley and Saylorsburg; Hamilton S was apparently not retained as a state highway. In April 1935, PA 12 was extended north to US 611 in Bartonsville, filling a gap between Snydersville and Bartonsville. By 1950, PA 90 was extended south to Easton, including the highway between Stroudsburg and Stockertown. On April 17, 1961, PA 191 was commissioned from the New York state line to US 309 in Center Valley. The route replaced PA 12 south of Stockertown (the rest would be superseded by the PA 33 freeway) and PA 90 north of Stockertown (the rest remained part of PA 115 until 1972). In Bethlehem, PA 191 was designated onto Wyandotte Street, crossed the Lehigh River, went onto Main Street, turned onto Elizabeth Avenue, and turned onto Linden Street or Nazareth-Bethlehem Pike north of the city. PA 191 was designated to replace PA 12 and PA 90 in order to provide a continuous route between Center Valley and the New York border as well as to reduce confusion with I-90 in the northwest part of the state. By 1970, when PA 378 was commissioned, PA 191 moved designations slightly in Bethlehem. Southbound PA 191 came from Nazareth, as Linden Street, and in Bethlehem, it turned west onto Union Boulevard. After it passed underneath I-378, the route turned south onto 3rd Avenue then onto the I-378 freeway. I-378 terminated at the bridge that crosses the Lehigh River and it continued as PA 191 (Wyandotte Street). By 1976, PA 191 was truncated to end at its current location and PA 378 (formerly I-378) replaced its former routing from
