Geotechnical investigation work is now complete on the Gateway Project.

The work is required to enter the engineering phase of the $5.6 billion Federal Transit Administration Capital Investment Grant. The grant would help fund the Hudson Tunnel Project.

A total of 75 geotechnical investigations were completed on the project, including 64 borings in New Jersey and New York over the past several years. A little more than half were done during the recently completed Phase 2 Supplemental Geotechnical Boring Program. Borings were completed along the future above-ground and tunnel alignments. Samples were taken at depths ranging from 48 ft to 505 ft.

Investigation work also included five Cone Penetration Tests, four Seismic Cone Penetration Tests, a marine geophysical survey in the Hudson River, and a surface-based geophysical survey along the Hudson Bergen Light Rail tracks in New Jersey.

“Finishing geotechnical investigations to reduce risk and provide certainty on where and how to did the first rail tunnel underneath the Hudson River in a century is a major accomplishment,” the Gateway Development Commission said in a joint statement.
