SEVEN GIANT TUNNEL SECTIONS ARE FLOATED OUT OF DRYDOCK

THE LOUIS-HIPPOLYTE LAFONTAINE TUNNEL IS THE LARGEST PRESTRESSED PRECAST CONCRETE STRUCTURE IN THE WORLD. THE TUNNEL ITSELF IS 4,560 FT LONG AND IT FORMS PART OF A 3.5 MI. BRIDGE-TUNNEL COMBINATION THAT CROSSES THE ST. LAWRENCE RIVER AT THE EAST END OF MONTREAL ISLAND. THE ENTIRE PROJECT WILL COST $60 MILLION, OF WHICH THE TUNNEL ALONE ABSORBS $42 MILLION. THE TUNNEL WILL CARRY 6 LANES OF TRAFFIC AND IS ONE OF THE LAST REMAINING LINKS IN THE TRANS-CANADA HIGHWAY. THE ARTICLE DEALS WITH THE CONSTRUCTION AND PLACING OF THE SEVEN 360-FT LONG TUNNEL ELEMENTS EACH WEIGHING 32,000 TONS. /CGRA/
