Advancements in Train Bridge and Underpass Construction

Salmon Arm, British Columbia, is witnessing a paradigm shift in train bridge construction with the adoption of innovative techniques such as architectural shotcrete over steel sheet piling. This method not only enhances the structural integrity and durability of the bridges but also contributes to the aesthetic appeal of the infrastructure for the Ross Street Underpass.

The Rondout Bypass Tunnel Shafts – Shotcrete Lining

The Rondout-West Branch Tunnel (RWBT), a segment of the Delaware Aqueduct (the Aqueduct), was built from 1937 to 1944 and provides about 50% of New York City’s total water supply. The tunnel is concrete lined and has a finished inside diameter of 13.5 ft (4.1 m). It is about 45 mi (72 km) in length and runs in the southeasterly direction from the Rondout to the West Branch Reservoirs.
