Railroad Bridge Modifications and Improvements

This project is anticipated to include modifications and improvements to two (2) railroad bridges (owned and operated by Union Pacific Railroad (UPRR) and referenced as UPRR #3 and Missouri Pacific (MoPAC)) to accommodate increased Kansas River flows in Kansas City, KS. The bridges were originally constructed in the early 1900s, carry two main line tracks each, and generally consist of four through truss spans and substructures supported on timber piles. Modifications to the UPRR #3 bridge generally consist of new lift screws, nuts, and guides to an existing electro-mechanical lifting mechanism. The original lifting mechanism was construction in the 1950s and includes a lift screw mechanism mounted to eight (8) towers along the bridge. The new lift screws will allow the bridge to be raised approximately two (2) feet higher than current conditions allow. Improvements to the MoPAC bridge include installation of a new lifting mechanism that will allow the static bridge to be raised approximately five (5) feet. Improvements will require superstructure modifications including truss end modifications, bottom chord retrofits, additional lateral bracing, and anchor bolt replacements. The new lifting mechanism is anticipated to be similar to the UPRR #3 electro-mechanical system with lifting screws to allow each span to be lifting independently of the others. Modifications to the substructure may also be required.
