The New Jersey Department of Transportation,focusing on maintaining the only link to the shore resort of Long Beach Island in Ocean County,NJ,rehabilitated four bridges and interconnecting roadway along coastal Route 72. Key to the project was rehabilitation of the Manahawkin Bay Bridge,a 1/2 mile long steel plate girder structure constructed in 1958 (see Figure 1). The project was significant in that it was one of the Dapartment's first projects involving rehabilitation of pin and hanger-type structures,of which there are a total of thirteen throughout the State,and also because pins were actually removed under two different temporary support conditions in both the evaluation and subsequent construction stages of the project.This paper will discuss the decision to replace pin and hanger components with stainless steel,and the methods of support and removal in both phases of the project.
