Tom Adams Bridge Rehabilitation


Tom Adams Bridge Rehabilitation

Client: Charlotte County

Location: Englewood, Florida

Construction Value: $2.6 million (Phase I) and $TBD (Phase II)

Completion Date: 2006 (Phase I) and estimated 2014 (Phase II)

Description:

The project goal was to extend the life of the bridge for an additional 50 years assuming regular, routine maintenance is completed on the structure. Rehabilitation plans were developed in Phase II based on the findings of the initial inspection done in Phase I. These plans called for 680 feet of integral pile jacketing providing cathodic protection for the piles, the replacement of 49,000 lb of structural steel on the bascule span, the painting of all of the structural steel, the restoration of over 1200 square feet of spalled concrete deck and the epoxy injection to seal almost 700′ of cracking in the concrete sea walls. The railing was upgraded to improve the safety for vehicles and expansion joint seals were installed to reduce future maintenance work. Permits were acquired from the US Coast Guard and from the Southwest Florida Water Management District that added special criteria to monitor and limit the turbidity and oxygen levels during construction in this Outstanding Florida Waterway. American was responsible for the design and permitting of this work, as well as the construction engineering and inspection. Future phases of this project will further improve the operation of the bascule bridge by building a new tender to increase visibility and replace worn mechanical and electrical component of the bascule machinery. The aesthetics of the bridge will be improved in the construction of the new tender house, decorative lighting and applying an aesthetic concrete coating.
