The Motor Carrier Division of the Maryland State Highway Administration (MDSHA) issues up to 150,000 oversize/overweight (OS/OW) permits per year for travel on more than 10,000 miles of roads. The routes pass over/under about 5,200 bridges. Carriers encountered significant delays as each jurisdiction had its own process for issuing specifically routed single trip and general 30- to 365-day multiple trip permits. To expedite the process, MDSHA implemented a statewide OS/OW permitting and routing system.


The USD 2.3 million project required strong project management and leadership by MDSHA. The result is a configurable solution that has been updated with new functionality to meet the needs of all the jurisdictional workflows. The system seamlessly integrates permit administration, routing, bridge analysis, and restriction management. Using Bentley’s automated permitting and routing products allowed the implementation to be completed several times faster than if MDSHA had developed the solution from scratch.


The new automated hauling permit system, “Maryland One,” is capable of achieving an automated issuance rate in excess of 73 percent, freeing up 10 full-time employees for other duties. The one-stop process is fast, easy, user-friendly, and accurate. Carriers will save USD 24.6 million per year by obtaining permits more quickly and avoiding costly fees, delays, and penalties. A higher compliance rate will decrease the number of illegal moves and increase safety for motorists on roads and bridges.


SUPERLOAD fulfilled MDSHA’s demanding permitting, routing, and analysis requirements. LARS Bridge created detailed models of structures within the system, which were loaded into SUPERLOAD for use in real-time bridge analysis. AssetWise InspectTech maintains the bridge inventory and inspection information, ensuring that SUPERLOAD has accurate bridge locations and clearances. Bentley CONNECT cloud services provide an expertly managed installation and a reliable, high-performance environment.

  • Asset performance modeling tracks asset use for every permit, revealing operational impacts that require maintenance.
  • Load tolerance modeling produces routing decisions that reduce the risk of damage.
  • With an average hourly load expense of USD 200, carriers will save USD 24.6 million per year and at least one hour on every move in the state.
  • The state will save about 10 minutes of manual processing time per permit, freeing up 10 full-time employees on an annual basis.
  • “Our new Bentley Maryland One System allows carriers anywhere in the world to use any device to apply for OS/OW permits 24/7, and have them routed, analyzed, and automatically issued up to configurable thresholds. We are confident that all clearances are checked, every bridge crossed is structurally analyzed, and all temporary conditions are considered. This is now done statewide, regardless of jurisdiction, through one single application, while still allowing each agency to manage its own road and bridge assets and review processes."
