Weight restriction season on Regional roads begins March 1st

EMILY MEEK, Communications Advisor, Regional Municipality of Durham

DURHAM: The Regional Municipality of Durham 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.

This affects vehicles which are heavier than 5,000 kilograms or five tonnes per axle.

This restriction starts March 1st and will run until April 30th. The actual final day may be adjusted, following periodic reviews of road and weather conditions near the end of the weight restriction season.

Signs will be erected on all Regional roads where these weight restrictions apply. Please refer to the complete map below for more information.

Weight restrictions are needed to prevent damage to 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.

Most public utility and emergency vehicles are exempt from weight restrictions. For more information, visit
