Bye, bye, Lake Champlain Bridge!

The demolition also was streamed live on the New York State Department of Transportation Web site, as well as the Web sites of several media outlets in New York and Vermont. A video of the demolition is available on the NYSDOT Web site at https://www.nysdot.gov/lakechamplainbridge.

NYSDOT engineers have been working with HNTB, an award-winning design consultant, to develop designs for the replacement bridge. HNTB, which has consistently ranked among Engineering News-Record's top design firms, fast-tracked the design phase of the new bridge, and presented its recommendations to the bridge Public Advisory Committee (PAC) as well as the general public earlier this month. New York and Vermont created the PAC in October 2009 to represent the public views regarding the old Lake Champlain Bridge and its replacement.

Both the PAC and the general public, through an in-person and an on-line survey made available by NYSDOT, viewed six renditions for a replacement bridge, and recommended a Modified Network, Tied Arch Bridge concept. The Modified Network, Tied Arch Bridge is a steel structure with a handle-like arch along the main span. Multiple redundancies in the design make this bridge significantly safer than the existing structure and ensure at least a 75-year service life. The design also is visually pleasing, complementing the mountainous back drop. A rendering of and more details about the Modified Network, Tied Arch Bridge can be found at www.nysdot.gov/lakechamplainbridge/alternatives.

Public preference will be one of many factors considered by NYSDOT and VTrans in the final determination of the design of the replacement bridge which is expected in January after further consultation with project stakeholders. Preliminary construction work for the new bridge is expected to begin in the spring 2010, and the new bridge is expected to be completed by late summer 2011.

New York and Vermont officials continue to work to establish a new ferry service in the vicinity of the bridge by the end of January.
