CONCRETE RIBBONS TO CARRY TRAFFIC OF GREAT HIGHWAY

Thin ribbons of concrete arching through the air, that will carry on a 42-foot wide pavement, traffic of one of the countrys chief east-west thoroughfares, the Lincoln highway, are skillfully depicted in this photograph of the George Westinghouse Memorial bridge nearing completion at East Pittsburgh.

The arches are more than half again as thin as those usually used.
