Info

On May 6, 1996 the twin spans of the new Coleman Bridge were actuated for the first of a series of successful trial openings. The Virginia Department of Transportation accepted ownership of the bridge later that month. This modern four lane movable bridge is equipped with today's highly reliable, industrial duty hydraulic and electronic system componentary. Long life, ease of maintenance, design flexibility, redundancy, environmental compatibility and operational assuredness are hallmarks of a desirable bridge drive system. Whether a new or rehabilitated bascule leaf or swing span bridge is to be constructed, the use of robust, industrial class hydraulic bridge machinery is a proven consideration when choosing a drive system for dynamic control of a moving span. - Page 10
