The Weehawken Tunnel Project consisted of the rehabilitation of an approximately 4,200 foot (1,280 meter) long, 23 foot (7 meter) wide excavated tunnel from a double-track freight rail to a double-track light rail system. The project also included a large underground station cavern, an approximately 40 foot (12 meter) diameter elevator shaft, and extensive portal slope stabilization and drainage measures. In order for the 120-year-old Weehawken Tunnel to be reconstructed, a deteriorating slope at the west approach to the tunnel needed to be stabilized.
Gall Zeidler Consultants provided Slope Stability analysis and design services for a heavyweight retaining wall made of individual cast-in-situ concrete blocks. In 2009, the design was honored with the Community Service Award for its excellence in construction and renovation of the Hudson-Bergen Light Rail Transit System (HBLRTS).
