Smiths Ferry Road. This alignment through Glasgow carried the Lincoln Highway until ca. 1926, when the present PA 68 was built on the north side of the railroad. The Lincoln Highway left the banks of the Ohio River on Smiths Ferry Road, which includes an old stone bridge over Upper Dry Run. It turned east on Tuscarawas Road through Ohioville, entering Beaver on Fourth Street and turning south on Buffalo Street to reach Third Street (PA Route 68). By 1929 this inland Glasgow-Beaver route was numbered PA Route 168, while the route along the river, never followed by the Lincoln Highway, was PA 68. Where PA 68 crosses the Pittsburgh and Lake Erie Railroad from Beaver into Bridgewater along Third Street and then the Beaver River on the ca. 1963 Rochester-Bridgewater Bridge, the Lincoln Highway instead ran along Bridge Street, just to the north, and crossed the Old Rochester-Bridgewater Bridge into Rochester. Continuing through Rochester to Pittsburgh, the Lincoln Highway left the Old Rochester-Bridgewater Bridge on Madison Street, turning onto Brighton Avenue, and then crossing the Pittsburgh, Fort Wayne and Chicago Railway (PRR) on New York Avenue. After running alongside the Ohio River on Railroad Avenue, the highway crossed the railroad again in Freedom (about a block north of Third Street), running through Freedom on Third Avenue. South of downtown Freedom, Third Avenue merges into the Ohio River Boulevard, also known as PA Route 65, which runs along the old Lincoln Highway into Conway. There the old highway went onto First Avenue and State Street, rejoining PA 65 in Baden. Further into Baden, the old highway left PA 65 again, onto State Street, becoming Duss Avenue in Harmony Township. At the Ambridge limits, this becomes PA Route 989, but the old highway turned west at 14th Street and then south on Merchant Street. Crossing Big Sewickley Creek from Ambridge, Beaver County into Leetsdale, Allegheny County, Merchant Street becomes Beaver Street, a brick road. Beaver Road and Beaver Street continues through Edgeworth, Sewickley, and Osborne, merging back into PA 65 at the border with Haysville. Sewickley officially changed the name of its piece to Lincoln Highway by an ordinance in January 1916, and Osborne, Edgeworth and Leetsdale soon followed suit, but that name is no longer used. In Glenfield, the highway crossed the Pittsburgh, Fort Wayne and Chicago Railway twice, once near the present overpass and again west of Toms Run
