WILL IT STOP AT TWO?

THE ARTICLE DISCUSSES IN GENERAL TERMS THE ARGUMENTS FOR AND AGAINST DIFFERING TYPES OF PROPOSED CHANNEL TUNNELS. THESE ARE: 1) BORED TUNNEL; 2) IMMERSED TUBE; 3) COMBINED TUNNEL/BRIDGE; 4) RAIL/ROAD COMBINATIONS; 5) MID-CHANNEL CITY DEVELOPMENT. TECHNIQUES FOR DESIGN AND CONSTRUCTION ARE EXAMINED. A NUMBER OF EXAMPLES ARE GIVEN SUCH AS THE CHESAPEAKE BAY BRIDGE, THE OOSTERSCHELDE BRIDGE, THE HONG KONG TUNNEL, ETC. POLLUTION PROBLEMS ASSOCIATED WITH THOSE HAVING VENTILATION, ESPECIALLY IN LONG TUNNELS AND THOSE HAVING HIGH GRADIENTS FOR RAIL TRAVEL, ARE MENTIONED TOGETHER WITH PROBLEMS ARISING FROM THE DIFFERENCES BETWEEN BRITISH AND CONTINENTAL RAIL LOAD GAUGES, TIDE FLOW AND NAVIGATION, AND SEDIMENT TRANSPORT, AND ITS SCOURING EFFECT. /TRRL/
