IDYLWYLD DRIVE OVERPASS AT RUTH STREET REHABILITATION
Location: Saskatoon, Saskatchewan
Project Type: Structures
About This Project
In 2014, the City reengaged ISL to conduct detailed testing to determine the best strategy and to design the rehabilitation. Seeking the most cost effective solution and aiming to reduce or eliminate costly shoring, ISL modelled and evaluated several options. The evaluation pinpointed two potential solutions: staged concrete removals to replace the top 100 mm of the deck (Option A); and spot repairs combined with an impressed current cathodic protection (Option B).
Additionally, upon further investigation during the 2014 predesign, ISL discovered a way to eliminate the joint from the overpass, implementing a unique semi-integral abutment approach to protect from further deterioration.
By intervening at an opportune time, providing cost effective rehabilitation recommendations focused on the underlying deterioration issues at the site, thoroughly reviewing all potential alternatives and delivering innovation to achieve the desired 50 year service life extension of the overpass, ISL successfully met the needs of the City and ensured that the project aligned with its Core Bridge Strategy and Strategic Goals of Asset and Financial Sustainability, Quality of Life and Moving Around.
