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.
O’Hare Plaza West Drive and Executive Garage Restoration
While infrastructure projects such as parking garages are often the last projects to be funded due to their utilitarian nature, they are important to the health of commercial properties since they are often the first impression for tenants and visitors. At O’Hare Plaza, the parking garage serves the 700,000 ft2 (65,000 m2) office complex.
The Neville Island Bridge Project
The Neville Island Bridge Rehabilitation project originally came out for bid in 2018. The bridge is located in Allegheny County, PA and within PennDOT’s District 11. In the bid package, it was noted that construction could not begin until a nesting pair of Peregrine Falcons had fledged their young, which translated to a late summer start.
Moyie Dam Repair: Back to the Future
Moyie Dam at Bonner’s Ferry in northern Idaho started initial construction just before WWII. They shut down construction during the war. After the war was over, the dam went into service in the late 1950s.
