The Virginia Department of Transportation is building a USD 45 million “superstreet” in Chester, Virginia, to safely and efficiently manage
congestion at the intersection of Route 10 and Chesterfield Road. The innovative design will eliminate left- and through-traffic movements
on minor cross streets at the busy intersection. Cross-street motorists will instead make right turns, then U-turn to reach their destinations.
McCormick Taylor designed the project using Bentley Descartes, Bentley Map, GEOPAK Civil Engineering Suite, and InRoads Suite to create
the base models. MicroStation and GEOPAK refined the design to accommodate the required turn lanes and ramps. Visual Solutions’ VisSim
ran traffic simulations to determine optimal turn lane lengths. A video featuring 3D animation helped win public support for the superstreet,
which will be completed by June 2018.
The Highways and Minor Ports Department of the Government of Tamil Nadu, India, retained L&T-RAMBOLL Consulting Engineers Limited
to design a cloverleaf interchange for the NH 4 ring road on the outskirts of Chennai. As part of a 30-kilometer greenfield corridor being
constructed at a cost of USD 165 million, the intersection connects five major roads, which will decongest traffic and disperse urban growth.
L&T-RAMBOLL’s scope of work included structural design of three major bridges, two minor bridges, and 100 culverts; 24 pedestrian
underpasses; five vehicular underpasses; two roads over bridges; three flyovers; and three interchanges. Using MicroStation and Bentley
MXROAD helped optimize the plan and profile to reduce project costs by 15 percent. Designing the cloverleaf interchange as a 3D model
also enabled cost-saving automated grading.
