"In September, 1899, began the work on the construction of the substructure for the Red River Bridge for the Kansas City Southern Railway at Index, Texas, ten miles north of Texarkana, Texas. The new substructure was located about one hundred feet up stream from the old one, consequently it was not necessary to maintain traffic during construction. The object of the new bridge was to replace a much lighter one, which was too light for the increased weight of rolling stock of the railroad company. The substructure consists of seven piers, including a pivot pier, and two abutments. The seven piers are concrete piers, which are supported by cribs and caissons of timber and portland cement concrete, sunk by the pneumatic process to and into the soft bed-rock, namely blue shale of impenetrable thickness" – p. 1.
