Commercial Vehicle Escort Information

The International Bridge Administration (IBA) requires an IBA provided escort for vehicles and permitted loads meeting any one of the following criteria:

    • EFFECTIVE 6.17.26:
      • Due to on-going seasonal maintenance activities, scheduled over-width loads on the International Bridge will be limited to 15 feet maximum from Monday to Thursday of each week.  Over-width loads in excess of 15 feet will be limited to crossings on Fridays only. 
      • Escorts must be supplied by the IBA due to the bridge’s two-lane configuration to ensure adequate traffic separation of oncoming auto and commercial traffic.
      • The driver of the vehicle to be escorted must contact the IBA upon or before reaching the bridge plaza for the scheduled escort.
      • Semi loads arriving outside the pre-scheduled crossing hours are completed solely at the discretion of the on-duty supervisor.
  • Bridge escorts must be scheduled a minimum of 24 hours prior.  
    • Unscheduled vehicles requiring escort may experience significant delays.
