Wildlife Crossing Design
- In 2011, HNTB with Michael Van Valkenburgh & Associates (New York) (MVVA) won the ARC International Wildlife Crossing Infrastructure Design Competition. The wildlife crossing design by HNTB with MVVA features a single 100-m (328-ft) concrete span across an interstate highway. The crossing bridge is planted with a variety of vegetation types, including a pine-tree forest and meadow grasses, to attract different wildlife species to cross. The modular precast concrete design means that much of the bridge can be constructed offsite and moved into place, shortening crossing construction time and minimizing disruption to the traffic flow.
