Road deterioration means spring is here

Judging by the amount of breakup occuring on the Bull Road in Bedell, its a good thing there are spring weight restrictions on New Brunswick's rural roads.

50 km/h is the posted safe speed for this curve on the Bull Road in Bedell. However, motorists must travel at slower speeds than that in order to avoid damaging their cars by hitting the frost heave and potholes in the curve.




It may be hard to see, but dips in the roadway such as this are caused by movement linked to frost in the ground.

Water laying in existing potholes may contribute to further deterioration of the roadway. In the thaw and freeze cycle, water seeps beneath the roadway, and it freezes upon drops in the temperature, busting the pavement.

If all of these cracks lead to breakup, then this section of the Bull Road will become a goatpath. There are already two minor potholes right in a row.
