Map of New Jersey Route 72 showing the bridge crossing Manahawkin Bay
The Dorland J. Henderson Memorial Bridge[1], familiarly known as the Manahawkin Bay Bridge, is a steel girder bridge that spans Manahawkin Bay, carrying traffic along Route 72 between Long Beach Island (LBI) and Manahawkin, New Jersey. The bridge starts at Manahawkin and ends at Ship Bottom on Long Beach Island. The bridge spans five land masses: the mainland, Long Beach Island, and three intermediate land masses, of which two are small and one is rather large.
[edit] Structural problems
Documented cracks due to metal fatigue have been found in structural members of the bridge. The New Jersey Department of Transportation (NJDOT) had previously taken steps to arrest the fatigue cracking, including modifying bridge girders and beams with drill stops. On 17 April 2007, Material Technologies, Inc. was retained by NJDOT to seek out fatigued members and prioritize their repair or replacement using its Electrochemical Fatigue Sensor system.[2]
