Immediate Closure Sussex County Bridge D-18 - Fenwick Road Frankford Township

Bridge Closure Advisory:
Sussex County Bridge D-18, Fenwick Road Frankford Twp.

During the recent engineering investigation of Sussex County Bridge D-18 it was determined the continued structural degradation of the bridge represents a significant operational safety issue to the traveling public. The currently deployed safety devices are not sufficient to ensure a reasonable level of operational safety for the continued use of this structure.

In the interests of public safety, the County has initiated immediate efforts to close this bridge to vehicular traffic. The closure will remain in place until such time as the deficiencies have been fully evaluated and remedial measures capable of restoring an acceptable level of operational safety have been implemented.

We regret we could not have provided more advanced notice, but paramount to our efforts is the protection of the traveling public’s safety.
