to justify their great amount of roads by having New York pursue the same ridiculous policy." However, Pennsylvania soon objected (after the final plan had been approved), on the basis that the U.S. Highways did not follow the existing auto trails. In particular, the Washington-Buffalo Susquehanna Trail had four numbers in Pennsylvania - US 111 to Harrisburg, U.S. Route 11 to Northumberland, U.S. Route 120 to Williamsport, and U.S. Route 220 north to New York, as opposed to the single number - Pennsylvania Route 4 - that had been assigned in 1924. Maryland did not object; US 111 was established in Maryland in 1926, from Baltimore to the Mason-Dixon line. By April 1927, Pennsylvania and AASHO had come to an agreement: US 111 was extended north, concurrent with US 11 and US 120 to Williamsport, where it took over former US 220 to New York. (US 220 itself was rerouted to its current alignment along what had been U.S. Route 711.) The extension took effect in the summer of 1928. Extension to New York US 111 was extended beyond its northern terminus at the Mason-Dixon line to Lemoyne; it ran concurrent with US 11 to Northumberland. The combined US 11 and US 111 crossed the Susquehanna River three times: the Market Street Bridge between Wormleysburg and Harrisburg, the Clarks Ferry Bridge north of Harrisburg, and the Route 11 Bridge over the West Branch Susquehanna River at Northumberland. Between the bridges, US 11 and US 111 used the main roads along the river. In Northumberland, US 11 and US 111 split at the intersection of Water Street (still US 11) and Duke Street (now Pennsylvania Route 147). U.S. Route 120 also passed through Northimberland on the present alignment of PA 147, running concurrent with US 111 to Williamsport. Along this section, US 111 and US 120 roughly followed the east bank of the West Branch Susquehanna River along PA 147, Pennsylvania Route 405 and a number of Quadrant Routes. However, between Milton and Muncy, the alignment was more inland, fairly close to the present Interstate 180. (Much of this road is still known as Susquehanna Trail.) At Water Street (now PA 405) in Muncy, US 111 and US 120 met U.S. Route 220, which joined the other routes the rest of the way to Williamsport. The three routes passed through Williamsport on Washington Street, Market Street, 7th Street, Hepburn Street and
