The project involves evaluation, coordination and design of a new 13-span railroad bridge. At more than 1,700 feet, the sizable structure will be built in stages due to site constraints using a roll-in construction method to accommodate a tight construction schedule. Project work includes development of inspection catwalks from above due to limited access below the bridge, girder spacing to allow tracks to be realigned on the bridge structure and shoring location development to achieve high production while protecting existing railroad operations.
The scope also includes relocation of two mainline tracks, the addition of a third mainline track and replacement of three structures carrying two mainline tracks. The design includes shoofly tracks for maintenance of operations, box culvert extensions, retaining walls, drainage, grading and major utility relocation to facilitate the improvements. A key component of our success is our ability to effectively coordinate with the UPRR and meet UPRR design requirements.
