DL&W = Delaware, Lackawanna & Western
"Built 1908-1911 as part of the 28.5 mile New Jersey Cut-Off." The last train was in 1978, and the tracks were removed in 1984. The state of NJ now owns the right of way. But the only they do is pay for state troopers to try to keep people off of it. [nj.com, Bridge Hunter] There is a longer viaduct three miles east of here.
"The Paulin's Kill Viaduct is a reinforced concrete structure, 1100 ft. long, composed of five 120-ft and two 100-ft arches carrying the new double track cut-off of the Delaware, Lackawanna & Western Railroad across the Paulin's Kill valley....The completed structure will contain 43,000 cu. yd. of concrete and about 500 tons of reinforcement steel....The base of the rail is about 110 ft. above high water and about 120 ft. above ordinary stages." The Cooper's loading is hard to read, but I think it is E50. [eBook, p66]
