Reduced Load Period and Permits

2024 Reduced Load Period (Town of Gravenhurst) begins March 4th, 2024

Load restriction in effect 5 tonnes per axle

During the annual spring thaw period, typically early March to late May, District of Muskoka municipalities place ‘half-load’ or ‘reduced/seasonal load’ restrictions on the majority of its roadways.

This year, the reduced load restriction in the Town of Gravenhurst comes into effect on  Monday, March 4th, 2024  (Restriction of 5 tonnes per axel). 

Every year, the Town (in partnership with the District of Muskoka) monitors thaw progression by utilizing patrol inspections and the forecast temperature data from Environment Canada and the local Weather Network. Depending on the progression of the thaw, restrictions may come into effect quickly, sometimes with only a few days’ notice. Once the pavement strength has been restored, the load restrictions are removed.

Purpose of a Load Restriction:

Each spring, as frost comes out of the ground and moisture comes out of the road bed, roads to become softer and weaker making roads susceptible to permanent damage caused by heavy loads. The seasonal load restriction protects the road and road base from damage caused by wheel loads of heavy vehicles and is ultimately intended to increase the lifecycle of municipal roadways.
