I-895 Connector Project
Richmond, Virginia
The I-895 over I-95 and the James River Project is part of the 8.8-mi. Rt. 895 Connector Project that will connect I-95 and I-295.
The $400 million high-level interchange is being constructed under a design-build contract. The segmental bridges consist of the east and west approaches, the river crossing over the James River and three ramp structures. The approaches are precast and built in balanced-cantilever. The west approach is being constructed with a self-launching overhead gantry. The river crossing has a 205-meter main span that is constructed cast-in-place using form travelers. The ramps are precast and built span-by-span using a self-launching underslung erection truss.
Construction of the nearly 200 cast-in-place segments ranging in length from 3.96- to 4.88-meters will be accomplished through simultaneous use of three pairs of form travelers. While most of the main piers consist of stiff twin-column arrangements, a single-column pier on the westbound bridge is being stabilized during construction using a unique cable-stayed arrangement.
Services provided by Finley McNary include design and details required for the contractor’s proposed erection scheme, shop drawing preparation, design of erection equipment, geometrical control plan and casting and erection manuals, post-tensioning calculations and procedures, casting curves, construction loading analysis and technical support.
