TICONDEROGA - Plans to demolish the existing Lake Champlain Bridge and construct a new span have been presented to the public.
The state Department of Transportation and Vermont Agency of Transportation held a series of meetings in Ticonderoga Dec. 12 to update area residents on the bridge, which was closed Oct. 16 because of safety concerns, and efforts to replace it.
The existing bridge will be torn down and a new bridge will be built at the same location in Crown Point.
NYSDOT contractor Harrison & Burrowes Bridge Constructors, Inc. has secured a subcontractor to demolish the existing bridge. Advanced Explosives Demolition, Inc. of Idaho will, working for H&B, plan for and execute the controlled explosive demolition of the steel truss bridge.
Officials said details on the bridge demolition will be well advertised and safe public viewing locations will be determined. The public will be prohibited from the area immediately surrounding the bridge, including the land, water and air. Access to certain roads also will be restricted to ensure public safety.
During the presentations Dec. 12, DOT reviewed the design criteria for the new bridge and the feasible bridge types available for consideration. People were asked for input regarding features that should be included in the design, such as sidewalks, bicycle lanes, lighting and materials used, as well as the style of the new bridge.
Stating that the goal is to move as quickly as possible to design a new bridge to replace the now closed one, officials of both NYSDOT and VTrans explained the pros and cons of the top five
