ABSTRACT: Highway 63:11 to the north of the Athabasca River Bridge in the urban service area of Fort McMurray, Alberta is situated on a narrow river terrace bench that The highway at this location is constrained between a meta-stable colluvial valley slope to the west and a steep eroded bank of the Athabasca River to the east. The highway expansion project at this location from 4 to 8 lanes created geometric constraints that required the construction of two parallel pile walls to confine the road cross section. The east side wall which is the subject of this paper is 320 m long and consists of up to 6 m high above-ground cast-in-place concrete wall supported on a below grade pile wall. The pile wall consists of 134 rock socketed piles and 113 high capacity grouted multi-strand tendons bonded into a limestone formation. The eroded slope above the river bank was protected using a high performance turf reinforcement mat to reduce the lateral movement of the wall. The paper provides a brief summary of the design and construction aspects of the east wall and includes a discussion about the instrumentation monitoring results.

RÉSUMÉ: acent. parallèle à la chaussée. Le muret Est, le sujet de cet article, à une longueur de 320 m et est composé de pieux en béton -dessus du niveau du sol et appuyé sur un muret enfouis. Le muret est composé de 134 pieux emboités dans un socle calcaireux et de 113 ancrages composés de tirants à câbles à n. Cet article résume de la conception et de la construction du muret Est
