Crews building the new span across the Mississippi River north of downtown St. Louis have hit an important project milestone - the completion of the twin 400-foot towers. Within a week, workers will start stringing cables from the towers to support the 1,500-foot main span.
"This is great," said project manager Greg Horn with the Missouri Department of Transportation. "These towers were one of the big things we had to get done."
There's no easy part of the project this massive, Horn said, but crews are feeling a sense of relief.
