Bridge L-158 is a disused railroad bridge over Muscoot Reservoir near Goldens Bridge, New York, United States. Built to carry New York Central Railroad traffic over Rondout Creek near Kingston, it was moved to its current location in 1904.
In 1960, it was taken out of service and the tracks removed. It is the only remaining double-intersection Whipple truss railroad bridge in New York. In 1978, it was listed on the National Register of Historic Places, the only bridge entirely within Westchester County to be listed in its own right.[2]
The bridge is located over an inlet in the reservoir approximately one half-mile (1 km) west of the Goldens Bridge station on the Metro-North Harlem Line and Interstate 684. It straddles the line between the town of Lewisboro on the east and Somers on the west.
NY 138 crosses the reservoir 500feet to the north. It is most clearly seen from here, although it can also be seen through the woods from commuter trains near the station.
It is surrounded by woodlands, part of the reservoir's protected watershed lands, all owned, like the bridge, by the New York City Department of Environmental Protection. The former route of the tracks is visible on both approaches to the bridge.
Both trusses are 163feet long, consisting of nine identical panels. The web is 32feet deep. Two concrete abutments support the bridge 12feet above mean water level.
Its pin-connected superstructure uses wrought iron Phoenix columns in its top chord and compression members. The end posts and upper chord are made up of six flanged cast elements riveted together. The intermediate verticals and lateral struts have four apiece.
The diagonals and lower chord have rectangular eyebars 4inchesto6inchesin (toin) wide. Round bars are used for the counters and sway braces. The ties are on iron stringers riveted to transverse iron floor beams. Both portals are decorated with quatrefoil brackets and finials.
The bridge was originally the smallest of three spans in a 1200feet viaduct-bridge combination along the former West Shore Line at the mouth of Rondout Creek in Kingston, 50miles to the north. It was built in 1883 by Clarke, Reeves & Company, a Philadelphia-based subsidiary of the Phoenix Iron Works as a 29adj=midNaNadj=mid double-tracked structure, known administratively within the Central as Bridge 141.
In 1904, the railroad built another bridge at the Rondout that could carry the entire load on one span. At the same time, New York City was beginning to buy, clear and flood land for its water supply system in the Croton River watershed. Railroads in the area were required, under their agreements with the city, to install bridges over any inundated areas at their own expense.
The railroad decided to move Bridge 141, now Bridge L-158, south to the new reservoir where it would easily bridge the gap needed for the Mahopac Branch from the former New York and Harlem Railroad main line. The branch, formerly the New York & Mahopac Railroad, served what had been a summer resort community in the 19th century. Since it was a single-track line, the bridge was rebuilt that way, its width reduced to 16feet.
Service on the Mahopac Branch continued until 1960. The tracks were eventually dismantled to and from the bridge, but the bridge itself remained. In 1976, a survey team from the Historic American Engineering Record found that it remained in good condition despite the lack of maintenance or use. Its presence on New York City watershed land, where public access is tightly restricted, has helped preserve it as well.
