New York Gov. David A. Paterson and Vermont Gov. Jim Douglas announced that the Modified Network Tied Arch Bridge concept is the preferred choice as a replacement for the Lake Champlain Bridge. Public preference was one of many factors considered as New York and Vermont chose the replacement bridge design, and played a significant role in the recommendation to proceed with the unique arch structure option.
“The selection of a design concept for the replacement of the Lake Champlain Bridge is a major step in restoring this critical connection between New York and Vermont,” Paterson said. “New York and Vermont’s transportation agencies identified the Modified Network Tied Arch Bridge as the overwhelming favorite of the people who live near and depend on this vital link. The next phase of design work will begin immediately as we continue our efforts to restore this important transportation connection.”
“Both the public and our bridge engineers agree that the Modified Tied Arch is an outstanding and appropriate design to replace the historic Lake Champlain Bridge,” Douglas said. “The new bridge will fit easily into the historic surroundings and be a source of pride for residents of both states for years to come.”
The Modified Network Tied Arch Bridge has a basket handle arch with a network cable arrangement and internally redundant box tie girders supporting a composite precast deck system. The bridge design has an expected lifespan of at least 75 years.
Construction will begin in the spring, and is expected to be completed by the end of summer 2011. Construction costs are expected to be approximately $75 million.
An online survey and public meeting held in both December and January revealed overwhelming public support for the Modified Network Tied Arch alternative.
The Public Advisory Committee, created by New York and Vermont to gather input on bridge replacement alternatives from the public, elected officials and other interested groups, stated their preference for the Modified Network Tied Arch option in December.
