Walsh is part of the design-build joint venture that is redeveloping LaGuardia Airport. The project includes a new 35-gate Terminal B, Central Hall, West Garage, related roadways and supporting infrastructure. The new LaGuardia Central Terminal B will feature dual pedestrian bridges spanning active aircraft taxi lanes - a first in the world - that connect the terminal to two island concourses. This islands and bridges design allows for improved airline circulation and gate flexibility, which will help reduce airport delays. From the western concourse bridge, a view of the Manhattan skyline epitomizes how the new terminal design uniquely reflects New York. The 1,300,000-square-foot Central Terminal B will be flooded with natural light at all levels, have short curb-to-gate walking distances, and have spacious and comfortable waiting areas with more seat capacity. The facility is expected to achieve LEED Silver certification.
