Wildlife Crossing Competition Finalists Propose Amazing Bridges


Olin Studio ARC Competition; PDF here
Designboom reminds us of the ARC International Wildlife Crossing Infrastructure Design Competition, , to promote "innovation in feasible, buildable context-sensitive and compelling design solutions for safe, efficient, cost-effective, and ecologically responsive wildlife crossings." It is proposed for Vail, Colorado, and the short list of five finalists was recently released. I think that drawing from Olin Studio is a stunner.

Balmori Associates
of New York built their bridge out of prefabricated wood; structurally it is the most interesting and architecturally looks like a contour map underneath. PDF Here

Toronto's Janet Rosenberg writes:

Every aspect of the crossing structure has been considered from an animal's perspective. We conceptualized the crossing with great sensitivity to how animals see, how they hear sound, what site characteristics they prefer.

Because like and noise from cars and trucks are distressing to wildlife, they integrated noise attenuation barriers, the high red walls, into the bridge. PDF here

Zwartz of the Netherlands seems more preoccupied with the structure, making a beautiful double curved arch. PDF here.


Michael Van Valkenburgh & Associates developed a precast concrete vaulting system that they claim will let them build the whole thing without ever having to close the road. PDF here
