This creative project integrated Redi-Rock wall products and a recycled railroad car to create a unique and attractive bridge at a development in northern Washington.
The owner of the property wanted to connect two of the man-made lakes but retain the current roadway, making a bridge necessary.
A local contractor recommended that the developer consider Redi-Rock to construct the fin walls and add an aesthetic appeal to the precast bridge abutments. The developer was impressed with the aesthetics and the engineering Redi-Rock offered.
Local Redi-Rock producer Wilbert Precast of Spokane, Washington, designed the project in collaboration with Coffman Engineers, also of Spokane. The owner wanted to use a 55 foot (16.8 meter) long steel railroad "flat" car that weighed 13,000 pounds (5896.7 kilograms) as the deck of the bridge. Designers specified 28,000 pound (12700.6 kilogram) precast concrete abutments that were 1 foot (0.3 meter) thick, 9 feet (2.7 meters) tall and 9 feet (2.7 meters) across. The precast abutments were covered with a Redi-Rock cobblestone veneer to match the Redi-Rock fin walls that flank the bridge.
The $35,000 project includes 120 Redi-Rock 41 inch (1041.4 millimeter)gravity series blocks.
The site encompasses 80 acres and required one and a half miles (2.4 kilometers) of road to access the building site. The developer quarried all of the necessary stone to build the roads on site, then used the quarries to build four lakes. A pad with utilities for a primary home were installed, along with space for facilities for family, friends and staff. The 70-acre parcel is on the market for $5 million.
