Grande Cache and Grande Prairie, AB
Client: CN Rail
Utilizing our specialized rail equipment, and working around the train schedules, Ruskin crews replaced 375 feet of ballast-deck bridge and converted 90 feet of open-deck to ballast-deck. This required 160 stringers to be replaced and 6 new frame bents to be constructed and installed. In addition, 694 deck ties were replaced; over 2000 tie plates were up-graded; 100 helper-stringers were installed; 35 caps and intermediate caps were replaced; 35 bracing and struts were replaced; 6 backwalls were replaced; 8 retaining walls were installed; over 50 piles were shimmed; and over 60 piles were posted or bolted. Project challenges included limited work blocks due to train traffic, temperature and weather extremes, and limited road access to some of the bridge sites.
