How will climate change affect the
region's transportation system?
Climate change places the tri-state metropolitan area’s low-lying
transportation infrastructure at increased risk of flooding. This
includes bridge and tunnel access roads, subway stations, tunnels,
highways, and New York City’s airports. In addition to the risk of
storm flooding, some coastal transportation facilities may be at risk
of inundation as the sea level rises.
• Many elements of the transportation and other
essential infrastructure systems in the New York metropolitan region
are located at elevations two to six feet above current sea level.
Storms frequently produce flood waters that exceed six feet. In
the event of a category 2 hurricane, the Holland Tunnel would be
inundated as seen in this picture.
Bridge access roads, entrances to road and rail tunnels, and many
transportation facilities are put in jeopardy by flooding, including
all three of the major New York metropolitan region airports (La
Guardia, JFK, and Newark-Liberty), the Holland Tunnel and Lincoln
Tunnel, the Passenger Ship Terminal, and major arteries like the FDR
Drive, the Brooklyn Belt Parkway, and the New Jersey Turnpike as it
crosses the Hackensack Meadowlands.
