“The Canarsie Tunnel Project”
The Canarsie Tunnel is a critical link in the New York City Transit system, carrying 225,000-240,000 riders each weekday on the L subway line between Manhattan and Brooklyn. In October 2012, when Superstorm Sandy hit New York City, the severe flooding that ensued caused considerable damage to the concrete duct banks, tracks, signal equipment and other electrical equipment in the tunnel.
Isabel Lopes became involved in the project when a revised repair plan became needed to accommodate directions from Governor Andrew Cuomo to avert the originally planned 15-month shutdown of the tunnel. Her presentation will give an overview of the major modifications to the tunnel, with a focus on the repair of the tunnel bench walls by means of structural fiber-reinforced polymer panels. The revised final design of the modifications to the tunnel successfully allowed construction to take place over intermittent tunnel closures on nights and weekends only.
Isabel Lopes is a structural engineer in the National Bridges and Structures Group at WSP. Isabel’s 14 years of experience in structural engineering includes analysis, design, inspection, and load rating of long span bridge and tunnel structures. Her responsibilities include preliminary and final design and analysis of bridge structures, construction support services for new bridge structures, structural repair and retrofit of existing bridges and tunnels, and inspection and load rating of existing structures.
Over the past 10 years following Superstorm Sandy, based on her strong analytical ability, Isabel has also worked extensively on flood repair and resiliency projects associated with the increasing effects of climate change. Her recent projects include the rehabilitation of two MTA Subway tunnels under the East River in New York City and the design for flood mitigation improvements and portal flood gates on a roadway tunnel in Lower Manhattan.
Our next speaker, on April 2, will be journalist and author Greg Steinmetz on “American Rascal: How Jay Gould Built America’s Biggest Fortune.”
