Project Description:

Triplett-King & Associates was responsible for the design of Ramps G & H and design management for Ramp E, all of which are multi-span, horizontally curved, and continuous for live load bridges at the interchange of Route 288 and I-64. The Route 288/I-64 Interchange is part of the $236 million design build project in Richmond, Virginia funded through the Public-Private Transportation Act of 1995 (PPTA). The superstructures for the ramps consist of curved structural steel plate girders with spans that range from 211 feet to 246 feet. The superstructures for Ramps G & H are supported by hammer-head piers and MSE high wall abutments. The begin bridge ends for Ramps G & H are supported by a single, shared MSE wall system with the highest portions of the MSE wall system being 70 feet tall, currently the tallest MSE walls in the Commonwealth of Virginia. Since the project was constructed in the design-build format, two submittals for each structure were required to facilitate construction of the substructures. The separate submittals enabled construction of the substructure components to take place while the final design, plan details, and fabrication for the superstructure components were completed. With an accelerated schedule, the ramps were designed in 10 months and were constructed in 20 months.
