The Landing Masonry Bridge, also designated Bridge 44.53, is a 136-foot (41 m) stone structure built in 1907 by the Delaware, Lackawanna and Western Railroad in Landing, New Jersey, United States. Located 44.53 miles up the rail line from Hoboken Terminal, the bridge carries the two-lane Morris County Route 631 (Landing Road) over the Morristown Line and Montclair-Boonton Line railroad tracks maintained by New Jersey Transit, and sits several hundred feet north of NJT's Lake Hopatcong Station. Now deteriorated and structurally deficient, it is to be replaced with a four-lane bridge by NJT and the New Jersey Department of Transportation.
