Red River Floodway Bridges on PTH 59N – MB

Dillon was retained by Manitoba Transportation and Infrastructure to provide construction oversight of two new major bridges and associated roadways over the Winnipeg Floodway on PTH 59N.

The existing bridge was constructed in 1964 and was in poor condition. The PTH 59N Bridge crosses over the Red River Floodway north of Winnipeg, Manitoba, and serves as a vital link for Eastern Manitoba and cottage country along eastern Lake Winnipeg, serving approximately 24,000 vehicles per day. This was the largest Contract Administration and Construction Inspection (CACI) project issued by Manitoba Transportation and Infrastructure to an Engineering Service Provider (ESP).

This multi-year project included bridge construction, road relocations and improvements, grading, paving, floodway excavation, and utility relocations. This work included monitoring the contractor for quality assurance, quantity management, and preparation of invoices.

The work included two new 304.5 m structures and new roadway adjacent to, and above, the existing alignment. The structures are 17.6 m wide, including seven-spans with continuous concrete NU girders, founded on steel H-piles with cast-in-place concrete abutments and a cast in place concrete bridge deck with a waterproofing system and an asphalt overlay. The new southbound bridge was constructed on the same alignment as the existing structure with the new northbound structure built on a new alignment. The project also consisted of approximately 3.0 km of new roadworks.

The Dillon team provided:

  • Overall project management.
  • Qualified Contract Administrators, a Resident Engineer, Construction Inspectors, for completion of Contract Administration and Construction Inspection of the new bridge over the Red River Floodway. For the bridge works, the Contractor completed the Quality Control role and Dillon completed the Quality Assurance role.
  • Senior Engineering review of project Request for Information’s (RFI’s), Submittals, Non-Conformance Reports (NCRs), Site Instructions (SINs), Items of Extra Work, construction issues (both general bridge and roadworks construction) and project documentation.
  • Safety training required during construction.
  • Monitoring of Contractor’s detailed construction schedules and identified probable delays to the contract completion.

The project, which encompassed a major Manitoba corridor, was completed with thoughtful consideration to detail, scope, innovation, budget and timelines. Dillon’s successful project delivery of this project continues to set the example for ESP delivery of bridge and roadworks Contract Administration and Construction Inspection services for Manitoba Transportation Infrastructure.
