Oversized and Overweight Vehicles Cause Bridge Damage

The U.S. state of Maryland faced the constant problem of structural bridge damage caused by oversized and overweight vehicles, which led to traffic jams, potential injury, and unexpected maintenance that depleted the state’s limited infrastructure funding. With structural information pertaining to bridge integrity siloed and difficult to access, the Maryland State Highway Administration (MDSHA) partnered with the Maryland Department of Transportation (MDOT) to create a system that would gather and analyze all necessary information in an easily accessible and secure online portal to improve oversize and overweight vehicle permitting and reduce future bridge collisions.

Gathering Data and Enabling Analysis

MDSHA and MDOT wanted the online portal to provide all bridge structural information, violation incidents, and related data in one location to make it easier for carriers to request permits and for the organizations to track permit issuing. The organizations also needed to ensure that carriers could quickly determine which bridges were safe for specific oversize/overweight vehicles to travel when requesting permits, saving them time and money. Violation tracking could identify frequent offenders, ensuring that compliant companies were not at a competitive disadvantage. However, simply gathering information in one place would not be enough. The agencies wanted a portal that would help improve bridge maintenance, promote continuity among state agencies, and provide accurate insight into the current state of Maryland’s bridges.

One Portal for Analysis and Decision-making

MDSHA and MDOT discovered that they could provide all organizations and carriers with the information and analysis that they needed by combining MDSHA’s in-house Strategic Asset Management solution with Bentley applications. Bentley’s AssetWise Inspections merged the collection, analysis, and management of bridge inspection data, improving decision-making. SUPERLOAD Bridge Analysis allowed carriers to automatically compare the exact structure and condition of a specific bridge with the size and weight of a vehicle that might cross it, speeding the permitting process. State officials can now track violations, detect patterns in the types of violations, and issue appropriate fines based on the nature of the violation and the frequency of incidents.

Sharing Benefits with Neighboring States

The portal’s simplified reporting and management lowers the time needed for route permitting and prevents mistakes arising from siloed data. As a result, the portal reduces the frequency of bridge collisions, which in turn has prevented costly bridge repairs and unnecessary detours through busy neighborhoods. MDSHA estimates that each prevented bridge strike saves an average of USD 50,000. But most importantly, the reduction in collisions with bridges has saved lives. Carriers also benefit by spending less time planning routes and obtaining permits, as well as saving transportation costs through optimized routes. State organizations can now make better maintenance and traffic flow decisions by tracking collisions and stay within their budgets. Logging violations and informing repeat offenders that their violations are being tracked encourages routing compliance. The Maryland organizations now share information on frequent violators with other states, which helps them cut down on bridge collisions and unexpected repair costs.

Project Playbook: AssetWise Inspections, LARS Bridge, ProjectWise, SUPERLOAD Bridge Analysis

  • Maryland’s route permitting process for oversize/overweight vehicles was cumbersome and dependent on data that was difficult to access.
  • Keeping up-to-date structural information and making it easily accessible greatly improved routing, reduced bridge collisions, and lowered repair costs.
  • The Maryland One portal helps state organizations make better maintenance and traffic flow decisions, which prevents unnecessary expenditures and lane closures.
  • State agencies can now track route violations by type and warn other states of repeat offenders.
  • SUPERLOAD serves as the core product in the oversize/overweight permitting and routing solution. It takes every analytical approach to facilitate safe movement and avoid bridge collisions.
