Abstract
An apparatus for opening a mechanical bridge. The apparatus includes at least two adjacent bridge spans where the first of the bridge spans is removable from its initial position and the second of the bridge spans is at least partially movable into the space originally occupied by the first span so that at least a portion of the second bridge span can be separated from yet a third adjacent span. This forms an opening between the second and third spans. Alternatively, a span can be moved laterally and then longitudinally to open a section of the bridge.
