Movable Bridge Machinery Inspection and Rehabilitation

Abstract

Age and marine environment, exacerbated by inadequate maintenance, have deteriorated movable bridge machinery and controls. The scope of six levels of field inspections performed to quantify and document the deterioration is described. For one of these, an intermediate level inspection recently adopted for the biennial bridge inspection program of New York State, the work items are outlined in detail. A discussion of the current approach to machinery and control rehabilitation in New York State concludes the paper.
