SHAFT FOUNDATIONS FOR THE NEW LONDON BRIDGE

THE NEW LONDON BRIDGE NOW BEING BUILT WILL COST OVER 4 MILLION AND WILL BE AN 860 FT LONG POST-TENSIONED CONCRETE STRUCTURE FORMED AS FOUR PARALLEL PRESTRESSED CONCRETE BOX BEAMS, EACH IN ITSELF A COMPLETE BRIDGE. IT WILL BE 105 FT WIDE AND WILL PROVIDE SIX LANES OF TRAFFIC AND TWO PEDESTRIAN FOOTWAYS OF 15 FT AND 26 FT WIDTH, UPSTREAM AND DOWNSTREAM RESPECTIVELY.

THE TWO SIDE SPANS ARE EACH 260 FT LONG AND THE CENTRAL SPAN 340 FT, DESIGNED AS A CANTILEVER WITH A CENTRAL SLUNG SECTION OF 107 FT. DETAILS ARE GIVEN OF THE CONSTRUCTION OF THE SHAFT FOUNDATION PIERS, COFFERDAMS, AND THE 900 FT TEMPORARY ERECTION GANTRY FOR INSTALLING THE NEW BRIDGE SUPERSTRUCTURE.
