New York I-678 Bridge Replacement
Our client asked us to design and provide a sixteen point Synchronous Jacking System to both raise and remove the existing bridges spanning over the I-678.
The bridges were raised and placed on a set of rollers, then pushed off to the side so that they could be demolished and taken away. The new bridge was placed on rollers and rolled into position then lowered into place using the same sixteen point Synchronous Jacking System.
This was done for both bridges on I-678. The Jamaica Avenue Bridge and Hillside Avenue Bridge job was a big success.
