The Darlington's Bridge at Delaware Station was a highway bridge that spanned the Delaware River in the community of Delaware, New Jersey (known locally as Delaware Station). A railroad bridge built by the Delaware, Lackawanna and Western Railroad in 1871 to replace an earlier 1855 timber span, this bridge was sold off when a new bridge was erected upstream. Henry V. Darlington, an Episcopal minister in Delaware and nearby Belvidere offered to buy the second-hand bridge for $5,000 (1914 USD, equal to $146,080 today). Darlington converted it into a highway bridge, using two fired members of the nearby Meyer's Ferry to be toll collectors. The use of this bridge subsequently increased; as a result, it became part of State Highway Route 6 in 1927 and U.S. Route 46 in 1936. In 1932, during the massive state takeover of bridges by the Delaware River Joint Toll Bridge Commission, Darlington refused buyout offers, bargaining his way up to $275,000 (1932 USD, equal to $5,898,415 today) before accepting the sale. This amount was far less than the sale prices of the nearby Belvidere-Riverton and Portland-Columbia Covered Bridge, which were accepted for $60,000 (equal to $1,286,927 today) and $50,000 (equal to $1,072,439 today) respectively. Around that same time, tolls on this bridge and Route 6 were eliminated, and the bridge continued to operate toll-free for twenty-one years, until the Portland-Columbia Toll Bridge was erected upstream at Columbia. The Commission finally ceased operations on the Darlington Bridge on April 3, 1954, and the bridge was immediately demolished.

The Paulins Kill (also known as Paulinskill River) is a 41.6-mile (66.9 km) tributary of the Delaware River in northwestern New Jersey in the United States. With a long-term median flow rate of 76 cubic feet of water per second (2.15 m³/s), it is New Jersey's third-largest contributor to the Delaware River, behind the Musconetcong River and Maurice River. The river drains an area of 176.85 square miles (458.0 km2) across portions of Sussex and Warren counties and 11 municipalities. It flows north from its source near Newton, and then turns southwest. The river sits in the Ridge and Valley geophysical province. The Paulins Kill was a conduit for the emigration of Palatine Germans who settled in northwestern New Jersey and northeastern Pennsylvania during the colonial period and the American Revolution. Remnants of their chiefly agricultural settlements are still found in local architecture, cemeteries, farms and mills, and the area remains largely rural. Flowing through rural sections of Sussex and Warren counties, it is regarded as an excellent place for fly fishing. The surrounding area is used for hiking and other forms of recreation such as observing birds and other wildlife.
