AN EXAMPLE OF EMBANKMENT CONSTRUCTION ON SOFT GROUND- CORUTENAY BAY CAUSEWAY

THE COURTENAY BAY CAUSEWAY PROVIDES A TWO LANE HIGHWAY LINK BETWEEN EAST SAINT JOHN AND THE CITY OF SAINT JOHN NEWBRUNSWICK. IT IS ABOUT ONE-HALF MILE LONG, 30 FEET IN MAXIMUM HEIGHT, AND CUTS OFF THE NORTH END OF COURTNEY BAY FROM THE SEA. SIGNIFICANT SITE CONDITIONS ARE FOUNDATION SOIL CONSISTING OF UP TO 90 FEET OF ORGANIC SILT AND SILTY CLAY, AND A NORMAL TIDAL RANGE OF ABOUT 28 FEET. THE CAUSE- WAY WAY, AS BUILT, UTILIZED ABOUT 114,000 CU. YDS OF QUARTZITE ROCK FILL ON A SAND AND GRAVEL BLANKET LAYER OF 78,000 CU. YDS. THE PAPER PRESENTS A CASE HISTORY OF DESIGN AND CONSTRUCTION WITH OBSERVATIONS OF SETTLEMENT AND PERFORMANCE. /CGRA/
