Indiana Southern Railroad
White River – Emergency Bridge Replacement
In November 2003, this Indiana Southern Railroad bridge over the White River experienced a settlement failure in one of the concrete/stone piers supporting a through truss girder span. This Indiana Southern Railroad bridge over the White River experienced a settlement failure in one of the concrete/stone piers supporting a through truss girder span. The Indiana Southern Railroad, part of the RailAmerica System at the time, asked Crouch Engineering for assistance in evaluating options for repairs and restoring the bridge to service. The Railroad was considering replacing or fortifying the existing pier. The Railroad had planned to replace the two pinned through truss spans over the White River in the future, at the cost of $1 million per span.
Crouch Engineering developed a creative solution and quick design that would not only replace the failed pier but also replace the low rated pinned through truss that was bearing on the failed pier, for about the same cost as the pier replacement.
Working closely with the Railroad, suppliers, and contractors, CEPC designed the new bridge piers and spans, obtained agency permits, ordered materials and bid out the construction of the replacement structure. CEPC performed all project management and engineering tasks including planning, survey, permitting, design, bidding, and construction project management.
Due to the low prices CEPC obtained for the replacement of the first truss, the Railroad decided to replace the second through truss span, for a total project cost to replace both through truss spans, and remove the failed pier for $800,000, rather than the $2.35 million in cost had a traditional approach been taken.
