Hanging Lake Viaduct’s design enhanced its
environmentally sensitive location as part of the I-70 Glenwood
Canyon project in Colorado. The project site is in an extremely
steep and narrow portion of the canyon. In addition to providing a
design that would protect the environment, traffic flow had to be
maintained. The solution was to build the viaducts from above. The
$34 million bridge was completed five months ahead of schedule.
