The new Lake Champlain Bridge, which replaces the Champlain Bridge and reconnects the towns of Crown Point, N.Y., and Chimney Point, Vt., is built from 4,021 tons of steel.

In the September MSC cover article (available now!), Theodore P. Zoli, chief bridge engineer at HNTB Corporation (and 2009 MacArthur Foundation Fellows winner and a 2010 AISC Special Achievement Award winner), describes the emergency replacement of the Lake Champlain Bridge.

 

The $76 million replacement structure reaches 2,200 ft across a narrow spot in Lake Champlain and was designed and constructed in just slightly more than two years to help restore mobility between Crown Point, N.Y., and Chimney Point, Vt.

 

Here’s an excerpt from the article:

 

Much has been written about the emergency replacement of the Lake Champlain Bridge - from the unprecedented collaboration between the bi-state owners, New York and Vermont, and the Federal Highway Administration to the successful pre-assemble-and-lift scheme.


But little has been said about the critical role steel played in expediting the project. Without steel, the preferred design alternative would have been impossible, the expedited schedule and the budget would have been in jeopardy and the project would not have been able to deliver a critical new lake crossing in record time.
