Additional Inspection and Maintenance Requirements. In addition to the inspection and maintenance procedures common with other bridges, bridges located over navigable waterways require special attention. Fixed span bridges and moveable span bridges have lighting required by the U.S. Coast Guard that may involve frequent maintenance. FDOT Design Manual – Bridge Structures. surface anywhere along the length of the bridge over the navigable water. For bridges with a designated navigation channel, minimum vertical clearance for navigation purposes is measured from the low point of the superstructure to the water surface at the edges of the designated navigation channel. High potential for a meander to migrate, or other channel instabilities. These and other aspects are valid considerations that affect bridge waterway openings. However, hydraulic computations are necessary to predict the performance and operation of the waterway opening at flood stages. Do not neglect hydraulic design.
