Interchange 14A Improvements
Tectonic provided Construction Engineering and Structural Engineering for this toll plaza widening project that required the demolition of an existing Toll Station Building. Tectonic designed all temporary supports (props, steel frames etc.), their connections to the existing structure and provided the construction sequence required for the reconstruction of the toll station building. Tectonic also verified the existing structure capacity after removal of the West walls of the building, part of the roof and the structural slab for all temporary construction loads.
The proposed improvements project consists of widening the toll plaza from 11 lanes to 12 lanes and replacing a 2-lane connector bridge to a 4-lane structure. A new flyover ramp will also be constructed and the traffic signal at East 53rd Street will be eliminated.
