Central Avenue Bridge
Posted August 27, 2011, by Joe Brennan (brennan [at] columbia [dot] edu)

A complex structure. It originally carried Central Avenue over the Morris Canal. The avenue was cut through about 40 years after the canal, and civic pride or some thing such forced construction of a difficult skew bridge in order to maintain the straight line of Central Avenue. The canal was closed in 1924, and the City Subway trolley line opened in 1935.

My diagram shows approximately the structure of the bridge. Note that at no point is this a simple pony truss bridge. Instead the trusses support the edge of the roadway where otherwise the structure is masonry wall and crossbeams.

Span A rests on masonry wall (brown), truss (dark blue), and a crossbeam. Span B rests only on masonry walls and crossbeams. Spans C D E rest on masonry wall, 3 trusses, and 2 crossbeams. The 2 crossbeams originally extended past the trusses to masonry columns on the south side of the canal, but now end under the ends of the trusses on columns built in the early 1930s when the City Subway was constructed.

The first photo shows the original south side with the crossbeams extending to the south side of the canal, circa 1929. The second photo shows almost the same view in August 2011.
