Description 

"The line crosses the St. Joseph River at the edge of South Bend on a 300- ft. span Pratt truss highway bridge. This bridge originally had an 18-ft. roadway, with a 6-ft. walk on each side cantilevered out from the floor beams of the bridge on brackets. The bridge was formerly carried on two trusses. The walk on one side was temporarily removed and a third truss erected on that side of the bridge, far enough from the existing truss on that side to give a clearance of 13 feet between the new and old trusses. The floor beams of the bridge, which are built-up I-beam girders, were then extended to the new truss and the walk cantilevered out from the ends of the extended floor beams. The ties for the car track were laid on 18-inch I-beam stringers on the floor beams. The track is protected by steel guards which divert traffic from the portion of the span carrying the car tracks. The cost of making the addition to the old bridge was about $8,000, while the estimated cost of the entire new bridge was $14,000."
