#TRAINS_MG_02432015 Ouachita River #Bridge

            My Louisiana home towns, twin cities, Monroe (East) and West Monroe (West) side of the Ouachita River.

Facility Carried / Feature Intersected
Railroad (Kansas City Southern) Over Ouachita River
Monroe: Ouachita Parish, Louisiana: United States

Structure Type
Metal Rivet-Connected Pratt Through Truss, Movable: Swing (Rim Bearing Center Pier) and Approach Spans: Metal 9 Panel Pin-Connected Pratt Through Truss, Fixed. 

Construction Date and Builder / Engineer
1882 By Builder/Contractor: A. M. Blodgett of Kansas City, Missouri (1907 Span) and Engineer/Design: C. Shaler Smith (1882 Spans)

This large truss bridge has a variety of span types and ages and has a complex history. Total length given is an estimate. It is difficult to date this bridge since the different spans appear to date to different times.

From west to east the bridge is configured as follows. First, a five-panel rivet connected Pratt through truss, about 125 foot span, dating to 1907 and built by A.M. Blodgett of Kansas City, Missouri. 

Next, a nine-panel pin-connected Pratt through truss of about 245 foot span length. It is possible this bridge dates to the original 1882 bridge. Next, the rivet-connected through truss swing main span of 295 feet. It is believed this span dates to 1906, which is the construction date given by TranSystems, who rehabilitated the swing span pier in 2007. 

Lastly, a nine-panel pin-connected Pratt through truss of about 245 foot span length. The swing pier has been supplemented by new modern steel and concrete designed to deal with the original pier shifting. The original piers on the bridge are a rare brick design and are assumed to date to the 1882 bridge.
