Program Overview

|
|
When the old Clark bridge at Alton, Illinois, became less fit for carrying
traffic across the Mississippi River, a team of designers and engineers was
called in to apply its knowledge of science and art to build a new bridge. The
team faced numerous challenges. How could team members
construct towers that would support the weight of the bridge, road, and
traffic load?
build a bridge while not interfering with river barge traffic?
design a bridge that would be within budget, aesthetic, and safe?
In this two-hour special, NOVA tracks the work of engineers, construction
crews, contractors, surveyors, and project managers as they build the new Clark
bridge from the ground up.
