The pilots were invited by the Seamen's Church Institute to find out what it will be like to manoeuvre around the Downtown and East End Bridges, part of the Ohio River Bridges scheme. Life-sized pilot wheelhouses were coupled with computer software and imagery to simulate the environment around the bridges during construction and after completion in a variety of river and weather conditions. "It's a tremendously helpful technology because it duplicates what it's like to approach and steer between the piers of a bridge," said Matt Bullock, the Kentucky Transportation Cabinet's interim project manager for the Ohio River Bridges Project.
