Spring is here — and so are the weight restrictions
Particularly in the northern part of the United States and into Canada, most everyone loves spring. While spring showers may bring May flowers, those showers and the melting snow also make the ground wet and soft. It is out of sight, but that same wet, soft, and unsupportive soil is also under the roadways – especially once off the main throughways. Because of this phenomenon, spring also brings spring weight restrictions.
Weight limits can be tricky. The interstates can have one limit, the state highways another, and local and secondary roads still another. How much weight a roadway can bear depends on the spending that went into the infrastructure in the first place. Interstates and primary highways have thick, well-graded foundations, bases, and surfaces. The final surface is often reinforced concrete. These surfaces remain strong and secure regardless of the season.
However, foundations and bases of secondary roadways are not as heavy or as thick. These roadways are often capped with asphalt, which by its nature is not as ridged as concrete, especially in thinner applications. With a wet and soft foundation during springtime, the roadway is not capable of supporting as much weight as in the dry summer or frozen winter.
Spring weight restrictions are most prevalent in the northern half of the United States and into Canada, but any state can impose restrictions. The use of portable scales on secondary roads is prevalent in the spring to enforce the weight restrictions. This enforcement is not meant to be a “gotcha” ticket. One of the highest line items in any state budget is for roadway infrastructure. Highway funds are tight, the states simply cannot afford additional the unnecessary expense to repair or replace roadways due to being overloaded in the spring.
Key to remember
The spring weight limit could be less than the posted weight limit of the road. It truly is a “traveler beware” situation. It pays to be informed. Most states maintain websites with the spring restrictions.
