Railroad Drive Arch Pipe Rehabilitation, Manassas Park, VA

The project consists of two 15'-6" span by 9'-5" rise corrugated plate metal arch pipes, one 188 ft and the other one 160 ft long. The inverts of each set of tunnels were corroded, and sections of the inverts were missing. The tunnels are cross under Railroad Drive with 3’ cover.

EU Design Consulting, LLC designed the rehabilitation scheme consisting of 4000 psi reinforced pneumatically applied wet mix concrete. The design assumed 100% section loss of the existing tunnel and considered AASHTO HL-93 as well as state legal loads such as VA Type 3, VA Type 3S2, Special Hauling Vehicles, and Emergency Vehicles.
