GRADE SEPARATION PROJECT AT OH-HARA INTERSECTION COMPLETED WITHOUT DISTURBING URBAN TRAFFIC

TRAFFIC CONGESTION AT URBAN AT-GRADE INTERSECTIONS HAS BEEN RECOGNIZED AS ONE OF THE MOST SERIOUS PROBLEMS IN ANY LARGE CITY. THE RECENTLY COMPLETED GRADE SEPARATION PROJECT AT OH-HARA INTERSECTION IN TOKYO WAS EXECUTED TO SOLVE SUCH A PROBLEM BECAUSE, WITH AN AVERAGE DAILY TRAFFIC COUNT OF 130,000, THE INTERSECTION HAD BECOME INFAMOUS DUE TO THE HEAVY AIR POLLUTION FROM AUTOMOBILE EXHAUST. DURING THE THREE YEARS OF CONSTRUCTION, TRAFFIC WAS NOT STOPPED. I.E., FROM RIGHT-OF-WAY ACQUISITION TO COMPLETION. DIFFICULTIES OF URBAN WORK PROJECT, PARTICULARY OF TREATMENTS FOR TRAFFIC FLOW AND VARIOUS UNDERGROUND FACILITIES, ARE DISCUSSED. THE SYNCHRONIZED CONSTRUCTION OF JOINT-USE CONDUITS AND STRUCTURES OF TOKYO EXPRESSWAY IS EXPLAINED. THE TRAFFIC SITUATION AFTER COMPLETION IS ALSO REPORTED. /JRS/
