Rehabilitation Project Overview
For the past six years, the NPS has been making temporary repairs to the bridge while planning a full rehabilitation. In February 2016, the Federal Highway Administration (FHWA) informed the NPS that despite these emergency repairs, without a complete rehabilitation, the accelerated deterioration of the concrete road deck would require a full bridge closure in 2021.
The construction work will replace the drawbridge span, rehabilitate the concrete approach spans, and replace the concrete deck. Workers will speed the work up by using prefabricated concrete deck panels. They will protect the bridge's historic appearance by removing, rehabilitating, and then reseting the stone curbs and light posts. They will also rehabilitate historic stone and metal cladding. We will replace the existing draw span with variable depth steel girders. The new, structural steel will significantly extend the useful life of the bridge and reduce maintenance costs.
