Construction resumed in earnest in 1867, 4 and the new Sand Patch Tunnel, one of the longest in the eastern United States, 4 opened to traffic in June 1871. 3 Severe geologic conditions resulted in the revising of the project to include just a single track, and ventilation in the tunnel proved to be an issue that required the creation of four vertical shafts for air circulation, although only three were completed. 4 Work was slowed with the development of the Civil War and problems of contractor bankruptcy, fraud, and legislative battles. The development of a 4,777-foot dual-track tube by Carr & Gould 4 at Sand Patch Pass began in May 1854, 1 which included the erection of 30 houses for workers above the tunnel itself. 2 It would require the construction of 100 miles of track through the Allegheny Mountains and a tunnel through Sand Patch Pass at the 2,258-foot summit. 2 The P&C between Connellsville and West Newton opened in September 1855, from West Newton and the Pennsylvania Railroad in Port Perry in 1857, and from Port Perry and Pittsburgh in October 1861.Īn extension of the P&C between Connellsville and Cumberland, Maryland, was authorized in 1853. The Pittsburgh & Connellsville Railroad (P&C) was incorporated in 1837 to connect Pittsburgh and Connellsville with construction beginning in 1847.
