Graham is excited to announce the completion of a major infrastructure project for Manitoba Transportation and Infrastructure (MTI). Located near Portage la Prairie, west of Winnipeg on the Trans-Canada Highway, this highway bypass project involved various stages and complexities to manage ongoing high volumes of traffic while allowing construction to progress. The bypass was a critical project for the Province of Manitoba.<\/p>\n
The work included replacing an overpass bridge, rehabilitating a bridge over CP tracks, constructing two highway roundabouts to safely merge traffic entering and exiting Portage la Prairie with high-speed highway vehicles, and reconstructing approximately 13 lane kilometers of adjacent Trans-Canada Highway. The primary driver was the need to replace the overpass bridge, which had exceeded its design service life and suffered multiple over-height vehicle impacts over the past ten years, leading to girder removals and lane restrictions. The new overpass is a two-span precast prestressed concrete box girder bridge founded on steel h-piles, with cast-in-place substructures and superstructure, and designed for a 75-year service life to meet all new applicable standards, including an increased vertical opening.<\/p>\n
Graham managed the coordination, quality, and safety of the work performed by our subtrade partners, including girder fabrication, erection, and extensive roadworks. Graham self-performed the bridge cast-in-place concrete, including large gang formwork, as well as the median barrier and drainage swale.<\/p>\n
The project required 1,400 linear meters of median barrier to be slip-formed which involved significant planning and collaboration. Alongside the median barrier, a 5,000 square meter cast-in-place concrete drainage swale was constructed using a modified Bidwell bridge deck finishing machine with out-of-the-box thinking and planning. This setup allowed for efficient and accurate placement of the swale concrete, ensuring strong quality control measures were met.<\/p>\n
Substantial Completion was achieved on November 3, 2023, with final seasonal restrictive work completed in spring 2024, with the bypass now fully opened to traffic.<\/p>\n
We commend our team and subtrade partners for their hard work and dedication to safety in completing this complex project.<\/p>\n","protected":false},"featured_media":255913,"template":"","meta":{"_acf_changed":false,"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":""},"categories":[],"tags":[569,12,551,16,292,550,341],"class_list":["post-255912","news","type-news","status-publish","has-post-thumbnail","hentry","tag-bypass","tag-construction-news","tag-highway-construction","tag-infrastructure","tag-manitoba","tag-portage-la-prairie","tag-road-construction"],"acf":[],"yoast_head":"\n
