Beginning Tuesday, March 1 at 6 a.m., seasonal weight and speed restrictions will be enforced by the following agencies:
- Barry County Road Commission
- Ionia County Road Department
- Kent County Road Commission (KCRC)
- Montcalm County Road Commission
- Oceana County Road Commission
- City of Kentwood
- City of Walker, Michigan
The intent of the restrictions is to protect the integrity of the road's structure when frost is coming out of the ground. As frost melts beneath a paved road, water is trapped between the pavement and the remaining ice layer beneath. This compromises the strength of the road and the weight it can sustain. When trucks and heavy equipment travel over a layer of concrete or asphalt that is not adequately supported beneath its surface, the road can incur significant damage.
Therefore, on roads with seasonal restrictions, legal loads must be reduced by approximately 35% and truck vehicle speeds reduced to 35 mph.
Enforcing the restrictions is based on multiple factors including solid frost depths, pavement and air temperatures, visual signs of pavement bleeding, pavement distress and the ten-day forecast. Neighboring cities and counties work closely together to discuss these factors and align enforcement, when possible.
