Due to corrosion of reinforcement and deterioration of concrete, the Arrigoni Bridge in Middletown, CT is in need of bridge deck repairs. The replacement of the concrete deck requires a demolition plan for the existing structure. To develop the plan, Team 22 considered alternative methods for deck removal and performed structural analysis to ensure stability of the bridge and the safety of its users during demolition. The methods considered include jack hammering, hydrodemolition, and saw cutting. After review of the cost and environmental impacts, saw cutting was selected. This method allows for a quick and easy penetration of the concrete deck that requires less than jack hammering and is less costly than hydrodemolition. Hydrodemolition also produced water runoff that could impact the river below. The demolition plan allows for continued use of the bridge for vehicle drivers and is pedestrian, worker, and environmentally friendly. Sidewalks will remain open for the duration of the project to maintain access for pedestrians. The structure was analyzed at multiple points to ensure stability of the bridge was maintained once the deck is removed.
