This paper describes the successful construction of new highway embankments over soft soils alongside existing high-traffic volume highways in the Greater Vancouver area of British Columbia. Highway 10 and Highway 15 intersect at Cloverdale in the City of Surrey. Reconstruction and upgrading of 23 km of these two highways have recently been completed as part of the Federal- Provincial Border Infrastructure Program. About 17 km of this upgrading is  located in the lowland area of the Nicomekl and Serpentine River floodplains which are underlain by soft and compressible fine-grained and organic soils. In the past, dyke and other embankment failures have been common in the area due to the soft soil conditions. The two projects consisted of highway widening from two lanes to four, construction of over 12 km of new embankment ranging in thickness from 1.5 m to 7.0 m, construction of nine new bridges, relocation of 2 km of railway and 1.2 km of water main, placement of embankment fills over existing sewer, water and gas utilities, and agricultural drainage improvements.
