The D & I Railroad Bridge T-648 Reconstruction project is underway. The General Contractor, L.G. Barcus & Sons, Inc., started work on June 12 and has completed access road construction, clearing, partial structure removal, and the start of the temporary causeway at the north end of the project. Riprap and access road material was provided by L.G. Everist, Inc. via 42 railcars. With recent permitting approvals for work to take place within the Big Sioux River, the contractor will be kicking it into higher gear this week with additional railcar deliveries of riprap for temporary causeway construction.

Hawkins removed and replaced eight separate bridges over two projects. Existing bridges were timber and replaced with H-pile supported precast structures that varied in lengths from 22 feet up to 100 feet. Pile driving was coordinated around train traffic and each bridge superstructure was completely replaced in a one-day track outage. Construction duration for all eight bridges was 5 months.
