The bridge proper at the overhead crossing with the Pennsyl-vania tracks is a steel truss through bridge of 125-ft. span, crossiuRthe Cy6-it. right of way of the railroad at an angle of 41 bridge rests on concrete abutments high enough to give 22^ measured above the rails of the RE.\K OF ELIDA SUB-STATION. The approaches are trestles, the bents of which are 16 ft. center tocenter. On each side of the bridge the inclined section of theapproach is straight witli a uniform grade of y/2 per cent to pointswithin i~5 and 225 ft., respectively, of the bridge; between the in-clined sections and the bridge are curves, the i7S-ft. curve on thenorth side being 18 deg. and the 22S-ft. curve on the south side 20deg. This structure was built by the LaFayette Engineering Co. Between Van Wert and Ft. Wayne the grade is ready for tracklaying, all bridges and culverts are in place and the riglit of wayis fenced on both sides. Overhead Equipment.
