ONTARIOS INTERWOVEN INTERCHANGE. SPIN 27 SPANS FOR MAJOR TRAFFIC HUB

THE SPADINA INTERCHANGE ON THE MACDONALD-CARTIER FREEWAY, GIVES METROPOLITAN TORONTO THE LARGEST AND MOST COMPLICATED INTERCHANGE IN CANADA. THIS $13 MILLION COMPLEX OF 27 BRIDGES AND RAMPS ADD UP TO 10 MILES OF TWO-LANE ROAD AND OCCUPY 150 ACRES OF LAND. IT WAS DESIGNED AND BUILT FOR THE ONTARIO DEPARTMENT OF HIGHWAYS AND THE METROPOLITAN TORONTO ROADS COMMISSION. PRIVATE BUSINESS IN THE YORKDALE SHOPPING CENTRE, WHICH IS SPECIFICALLY SERVED BY THE INTERCHANGE, ALSO CONTRIBUTED PROPORTIONATELY TO THE COST. DESIGN EVOLUTION' /1/ CLOVERLEAF DESIGN WAS FIRST PLANNED BUT DROPPED BECAUSE OF INADEQUACY IN LIGHT OF TRAFFIC VOLUMES ESTIMATED, /2/ TURBINE DESIGN, ABANDONED BECAUSE OF EXTREME COST AND DIFFICULTY IN SERVING THE YORKDALE PLAZA, AND /3/ TURBO-LEAF, COMBINING A CLOVERLEAF AND TURBINE, BECAME THE BASIS FOR THE FINAL DESIGN. /CGRA/
