The fictional Madison Bridge is represented by the Astoria-Megler Bridge on the Columbia River, the longest continuous truss bridge in North America.
Plot
Engineer Cal Miller's unauthorized attempt to close off the dangerously unstable Madison Bridge is foiled by the police pursuit of a robbery suspect. The chase ends in a multi-car accident in the middle of the bridge, which begins falling apart during the confusion. Miller organizes a rescue operation for the handful of bystanders who find themselves stranded with the armed suspect and a wounded policeman on a short stretch of crumbling pavement high atop a single collapsing pylon.
The casting of Eve Plumb and Barbara Rush was announced in July 1979.[2]
Reception
The show fared poorly in the ratings against the last episode of MASH, which attracted the largest audience for any single show in television history. It had 10 percent of the viewers in New York, 12 percent in Los Angeles and 5 percent in San Francisco.[3]
