COWI and BOT Construction Group reach major milestone in William Halton Parkway Bridge construction

[Toronto, 2 May 2024] – Leading international engineering consultancy COWI in collaboration with BOT Construction Group has achieved a critical milestone in the construction of the North Bridge by successfully achieving continuity within Spans 2 and 3 of the bridge’s superstructure between the segmentally built cantilevers. This achievement marks a significant step forward in the completion of the William Halton Parkway extension project in Oakville, Ontario.

At this milestone, the team has reached the balanced ends of the West and East cantilevers of the North Bridge, casting a total of 50 segments, 2 pier tables, and an end span section at the East Abutment which an end diaphragm. To achieve the continuity in the superstructure, the closure segments for span 2 and span 3 have been cast with post-tensioning tendons stressed through the closure concrete.

As construction progresses, all form travellers, except for the one on the extended west cantilever of the West Pier, will be demobilized and relocated to the South Bridge for the start of its balanced cantilever construction. BOT will continue casting the “extended” west cantilever in the upcoming weeks, utilizing the temporary stay tower and stay cables to provide additional support during the bridge casting process.

Ivan Liu, Senior Bridge Engineer, COWI in North America, said: “We are excited to reach this significant milestone with the BOT team on the construction of the North Bridge. From our experience, getting to this stage on a segmental bridge project is not an easy task and it shows the extensive effort, quality, and skill of the BOT team. We’re proud to be able to work with the BOT Construction Group to help them deliver this complex bridge structure thru our experience and expertise on segmental bridge construction. We appreciate the partnership with BOT Construction and look forward to the continued progress of the William Halton Parkway bridges.”

The two new bridges over Sixteen Mile Creek, part of the William Halton Parkway extension project, are being constructed using a cast-in-place segmental construction technique, employing a movable form traveller system. Once completed, the bridges will span 280 meters and each host two lanes and pedestrian walkways, providing vital connectivity between Third Line and Neyagawa Boulevard.

COWI, responsible for construction analysis, geometry control, erection manuals, and construction support, along with the design of temporary work structures, is working closely with BOT Construction Group to ensure the successful completion of these significant infrastructure assets for the growing Halton region.
