The route crosses the Tunkhannock Creek and heads into farmland before heading into forested areas to the north of the East Branch Tunkhannock Creek and intersecting the northern terminus of PA 407. The road continues through forests with some homes and heads across the creek. PA 374 runs south of the East Branch Tunkhannock Creek and comes to an interchange with I-81. Past this interchange, the road heads northeast through more wooded areas with some residences, crossing into Clifford Township. The route runs through areas of fields and woods with a few homes, coming to an intersection with PA 106 in Royal.

History
The portion of PA 374 between Dimock Corners and Herrick Center was chartered as a private turnpike called the Cohecton and Great Bend Turnpike on March 29, 1804. This turnpike was planned to run between Damascus Mills and the summit of Moosic Mountain. The Cohecton and Great Bend Turnpike was completed in 1811. The turnpike, along with the Newburgh and Cochecton Turnpike, served as the main route between Newburgh, New York and Western New York. Traffic along the Cohecton and Great Bend Turnpike was reduced by both the completion of the Erie Canal and the Erie Railroad. When Pennsylvania first legislated routes in 1911, what is now PA 374 was not given a number. By 1930, the section of the current route between US 106 in West Clifford and PA 70 in Herrick Center was an unnumbered, unpaved road. The road between PA 92 in Glenwood and US 106 in Royal was paved in the 1930s. In addition, the section along Old Newburg Turnpike was designated as part of PA 371 in the 1930s, which was paved. By 1941, the roadway was paved between US 106 in West Clifford and PA 371 in Dimock Corners. The PA 371 designation along the road between Dimock Corners and Herrick Center was removed in 1954. PA 374 was designated in April 1961 as part of a decision to designate several new traffic routes to interchange with I-81, which had been recently constructed. When created, the route ran from PA 92 in Glenwood east to US 106 in Royal. PA 374 was extended east to PA 171/PA 371 in Herrick Center in the 1980s.
