New Guide to Bridge Hydraulics, Third Edition Project has Launched

Tuesday, March 22, 2022

A new Transportation Association of Canada (TAC) project to develop a third edition of the Guide to Bridge Hydraulics has launched. The project was proposed by TAC’s Structures Committee, which reports to the Infrastructure & Asset Management Council.

The Guide to Bridge Hydraulics helps bridge design, construction, and maintenance professionals account for hydraulic and hydrologic considerations in bridge siting, layout, design, evaluation, operation, and maintenance. The Second Edition of the Guide was published in 2001 and requires updating to better address the risks associated with a rapidly changing climate. The new Third Edition will include provisions related to climate change, and incorporate updates to reflect research, best practices and regulatory requirements that have emerged in the last two decades.

The unprecedented flooding in British Columbia in 2021 illustrates how floods and erosion are vital considerations in the design, construction, and maintenance of bridges because they can damage structures or even cause them to fail, as well as the importance of the Guide and the need to keep it current.

A Project Steering Committee is now being formed with representatives of nine TAC member organizations that have committed funding to undertake the work:

  • Alberta Transportation
  • British Columbia Ministry of Transportation and Infrastructure
  • City of Winnipeg
  • Ministère des Transports du Québec
  • National Research Council Canada
  • New Brunswick Department of Transportation and Infrastructure
  • Northwest Territories Department of Infrastructure
  • Nova Scotia Public Works
  • Prince Edward Island Department of Transportation and Infrastructure

There are still opportunities for interested organizations to help fund the project and participate on the Project Steering Committee.

A request for proposals to conduct the work will be issued by TAC this spring and a final publication of TAC’s Guide to Bridge Hydraulics, Third Edition is expected in 2025.
