Defining the Term Intercity Bridge
An intercity bridge refers to any bridge structure located within the jurisdictional boundaries of a city or urban municipality that is subject to specific weight restrictions and traffic regulations. These bridges are typically part of the local road network rather than state or federal highways. Unlike interstate bridges, which are designed to accommodate higher gross vehicle weights and long-haul freight traffic, intercity bridges often have lower load ratings due to age, design limitations, or municipal policy.
Weight Limits and Legal Implications
In many U.S. states, including Ohio, the legal gross vehicle weight (GVW) allowed on interstate highways is commonly set at 68,500 lbs for certain commercial vehicles. However, once a truck enters city limits and travels over intercity bridges, the permissible GVW may drop to 62,500 lbs. This reduction is not arbitrary—it reflects the structural capacity of older or narrower bridges and the need to minimize wear on urban infrastructure.
Operators must be aware of these thresholds because exceeding them can result in fines, citations, or forced offloading. For example, a dump truck with a tare weight of 34,500 lbs may only carry 28,000 lbs of payload within city limits, compared to 34,000 lbs on the interstate.
Terminology Clarification
A common point of confusion is whether culverts—underground drainage structures beneath roads—are considered intercity bridges. Technically, a culvert is not a bridge unless it spans a defined waterway and meets specific structural criteria. However, in enforcement practice, any load-bearing structure within city limits that supports vehicular traffic may be treated as an intercity bridge for weight regulation purposes.
Enforcement and Certification
Weight enforcement is typically carried out by state DOT officers, but local law enforcement such as county sheriffs may also conduct inspections. However, not all deputies are certified to perform full DOT inspections. For instance:
Stories from the Road
A truck operator in Barberton, Ohio shared that his dump truck, weighing 34,500 lbs empty, often skirted the legal limit when hauling asphalt into city projects. He once crossed a small bridge on a state route and was flagged by a local deputy. Fortunately, the officer lacked DOT certification and could not issue a formal citation. This incident underscores the importance of knowing both the infrastructure and the enforcement landscape.
In another case, a paving company in Pennsylvania retrofitted their fleet with onboard scales to monitor axle weights in real time. This allowed drivers to adjust loads before entering urban zones, avoiding fines and improving compliance.
Recommendations for Operators
Intercity bridges represent a critical junction between infrastructure and regulation. Understanding their role in weight enforcement helps operators stay compliant and protect aging urban structures. As cities continue to modernize their roadways, the definition and regulation of intercity bridges may evolve—but for now, awareness and preparation remain the best tools for safe and legal transport.

Terminology Clarification
- GVW (Gross Vehicle Weight): The total weight of the vehicle including cargo, fuel, and passengers.
- Tare Weight: The empty weight of the vehicle without cargo.
- Interstate Bridge: A bridge on a federally maintained highway system.
- Intercity Bridge: A bridge within city limits, often maintained by local authorities.

Enforcement and Certification
Weight enforcement is typically carried out by state DOT officers, but local law enforcement such as county sheriffs may also conduct inspections. However, not all deputies are certified to perform full DOT inspections. For instance:
- Fuel Sampling (Fuel Dipping): Only certified inspectors are authorized to test for off-road diesel use, which contains higher sulfur content and is not taxed for highway use.
- DOT Certification: Officers must complete federal training to legally inspect commercial vehicles and operate scale equipment.

Recommendations for Operators
- Install onboard weight sensors to monitor GVW dynamically.
- Consult municipal maps to identify restricted bridges and culverts.
- Verify enforcement authority before submitting to roadside inspections.
- Avoid off-road fuel in on-road vehicles, even for agricultural use.
