Newark Drawbridge

The Newark Drawbridge, also known as the Morristown Line Bridge, is a  railroad bridge on the Passaic River between Newark and Harrison,  New Jersey. The swing bridge is the 11th bridge from the river's mouth at Newark Bay and is 5.85 mi upstream from it. Opened in 1903, it is owned and operated by New Jersey Transit.

History
Rail service across the river was generally oriented to bringing passengers and freight from the points west over the Hackensack Meadows to Bergen Hill, where tunnels and cuts provided access to terminals on the Hudson River.

In 1836, the Morris and Essex Railroad established a right-of-way from the west at Orange to Newark, from where it used the New Jersey Rail Road at Centre Street to cross the river and travel east to its terminal at Paulus Hook on the waterfront in Jersey City. By 1855 it built its own bridge across the Passaic. By the early 1860s, the railroad had established the alignment across the Kearny Meadows and began using the Long Dock Tunnel to Hoboken.

In the early 1900s railroad elevated the line approaching the river which previously ran at grade along Division Street in Newark and built the current bridge. Completed in an earlier phase, the bridge was later shifted 35 ft upstream on the new alignment.

In 1945, the Morris and Essex Railroad officially merged into the Delaware, Lackawanna and Western Railroad. DL&W merged with the Erie Railroad in 1960 to form the Erie Lackawanna Railroad, which was absorbed by Conrail in 1976; New Jersey Transit has operated all passenger service since 1983.

Operations
The lower 17 mi of the 90 mi long Passaic River downstream of the Dundee Dam is tidally influenced and navigable, but due to the limited maritime traffic the bridge is infrequently required to open. Since 1998 rules regulating drawbridge operations require a 24-hour notice. The bridge at milepost 7.48 is used exclusively by New Jersey Transit rail operations for the Montclair-Boonton Line and both branches of the Morris and Essex Lines, the Morristown Line and the Gladstone Branch. It is situated just east of Newark Broad Street Station, the first stop after the lines travelling west from Hoboken Terminal and Secaucus Junction converge. In 2004, NJT contracted a study to determine the condition of the bridge and to begin long-term planning for its future replacement. In 2009-2010, the bridge underwent $23 million project for maintenance and repairs, funded by the agency and performed by Skanska.
