The Regional Municipality of Durham’s 2022 weight restriction season has ended as of April 30. This affects vehicles that are heavier than 5,000 kilograms or five tonnes per axle.
Signs will be removed from regional roads where these weight restrictions no longer apply.
However, the region asked drivers to note that some roads may have year-round weight restrictions applied. Please refer to the complete map for more information.
Durham Region and local area municipalities restrict the operation of motor vehicles on designated roads during the spring weight restriction season, as per the Highway Traffic Act and Regional By-law 26-2018.
Weight restrictions are needed to prevent damage to regional roads. In the spring, frozen roads start to thaw making the pavement on some roads temporarily lose strength and become unable to support vehicles heavier than 5,000 kilograms or five tonnes per axle.
