Miller Highway Tunnel, 62nd - 63rd Street
New York, NY
This job is part of a long term project to relocate sections of the existing West Side Highway under Riverside South Boulevard. Diverting traffic into the tunnel will reduce traffic on the Boulevard providing better land use above, creating new parklands, pedestrian walks and bicycle paths that are being constructed along the waterfront creating access from the residential towers.
This project involved massive foundation excavation for H-pile installation and construction of the concrete foundation. The 3 sided 260 foot structural box was constructed with 3 foot thick walls, 30 feet high and a 3 foot thick roof slab. Heavy steel reinforcement was required on all sides. Formwork for the concrete roof construction utilized a rolling scaffold/shoring system which minimized cost and accelerated the project. Also, the fabrication and installation of a temporary bridge from the tunnel roof to 62nd Street provided uninterrupted service for the construction of Building J at Riverside South Boulevard. A new 42” diameter storm sewer and 18” sanitary sewer was constructed from 62nd Street to 63rd Street to service Building J.
