Natcher Bridge

PROJECT OVERVIEW


 A 4,510' cable-stayed, twin tower, bridge project. The bridge spans the Ohio River and Indiana 66 near Rockport, Indiana, and Owensboro, Kentucky (US 231). The bridge will have two main towers, each 345 feet above the surface of the river. It will be 4,500 feet long with four 12-foot-wide traffic lanes.   The Kentucky Transportation board will over see the project.  The contractor is Traylor Brothers Inc.  who bid the job at $55.5 million dollars. This cable-stayed bridge is one of only about twenty in the United States.

This project is now scheduled to be done summer 2002 after taking into account weather and other delays.  The projects is expected to come in under budget.  Due to some technological advances in bridge building the cost of the bridge is now expected to be $54 million a savings of over $1 million. Some interesting notes on this bridge:

To keep the concrete from cracking, ice was brought in by trailer loads to mix with the concrete, and cold river water was pumped through pipes inside.

“Concrete this thick heats up,” Owens said. “If the outside and the center cool at different rates, you get cracks. When they built Boulder Dam, they pumped cold water in pipes the same way.”

In the winter, electric heaters and tents were used to keep the temperature around the concrete headers at around 45 degrees.

The project has reached the halfway point and should be complete by the end of 2000.
