The amount of work per mile varied; the largest share apparently went to David W. Flickwir, whose Section 3 included Roseville Tunnel and the eastern half of the Pequest Fill.
To accommodate the labor gangs, deserted farmhouses were converted to barracks, with tent camps providing additional shelter.
These workers, many of whom came from Italy and other foreign countries or other parts of the U.S., were recruited and would move on to other projects after their work on the Cut-Off was completed.
These workers were viewed with suspicion by the local populace in Warren and Sussex counties, with the town of Blairstown going as far as hiring a watchman at $40 per month for the duration of the project.
With several thousand men working on the project for over three years, the area all along the Cut-Off, and as far west as Portland, Pennsylvania, benefitted financially.
In 1910, for example, five workers were killed in a single blasting mishap near Port Morris, one of several deadly accidents that involved dynamite.
[1] Depending on the fill size, material was dumped from trains that backed out onto track on wooden trestles or suspended on cables between steel towers.
It was at its maximum height 110 feet (34 m) tall and was 3.12 miles (5.0 km) long, requiring 6,625,648 cubic yards (5,065,671 m3) of fill.
[4] Contractor Flickwir, whose section included Roseville Tunnel and the eastern half of the Pequest Fill, worked around the clock during the summer of 1911 when construction fell behind schedule.
In 2008, K-07 was replaced by a modern two-lane bridge of similar design about midway between the ends of the cut (MP 47.8), near its deepest point, where the line is on a 2° curve (70 mph, 113 km/h).
[8] McMickle Cut is within the section of the Cut-Off that is being rebuilt by NJ Transit for rail service to Andover, which is slated to open in 2018.
Lack of maintenance has allowed the area to drain increasingly poorly and meet the technical definition of wetlands.
[6] Located between mileposts 48.3 and 49.0 in Byram Township, it sits on a tangent (straight) section of right-of-way just west of McMickle Cut and just east of Bradbury Fill.
In 2012, a single track was relaid through the cut as part of NJ Transit's plans to restart rail service in or after 2026.
[7] A dam was built under the fill on the north side of the embankment, creating Dallis Pond, which flows into Lake Lackawanna.
Section 3 was assigned to contractor David W. Flickwir, who built miles 50.2–55.8, from Lake Lackawanna to the center of Pequest Fill.
Most of the material for the 0.5-mile (0.64 km) fill was excavated from the surrounding low-lying area drained by Pumpkin Run; several of the borrow pits have since become ponds.
Located between mileposts 51.8 and 52.3 in Byram Township, Colby Cut was created by removing 462,342 cubic yards of fill material.
[9] In March 1906, Colby proposed to Lackawanna President William Truesdale that the railroad should put a train station for the Cut-Off on his property, near a "Roseville Lake" (probably Wright's Pond, which is just east and north of the tunnel).
Truesdale had Colby contact the chief engineer, Lincoln Bush, to investigate the idea, but the proposal appears to have gone no further.
Section 4 was assigned to Walter H. Gahagan: miles 55.8–60.8, from the center of Pequest Fill westward to Johnsonburg station.
[9] Part of the north side of Armstrong Cut collapsed in 1941, completely blocking the Cut-Off, and causing all traffic to be diverted to the Lackawanna Old Road for a month while the embankment was excavated back.
[6] Located near milepost 64.8 in Blairstown Township, the cut was constructed by removing some 578,000 cubic yards (442,000 m3) of fill material.
Located between mileposts 65 and 65.3 in Blairstown Township, the fill was made of 293,500 cubic yards of material, much of which was obtained from nearby Jones Cut.
This bridge over Paulinskill and the New York, Susquehanna & Western Railroad was the world's largest reinforced concrete structure at its completion.
Built by Smith, McCormick Co., Section 7 included miles 70.8–74.3, from the west end of Paulinskill Viaduct to Slateford Junction.
