• Define your vehicle
• Use Google Maps to find a point to point route 
• Use the process to analyze your route for bridge clearances and NEW bridge load analysis (click here for details) based on state bridge data provided to the FHWA.
• Review warnings for each identified bridge clearance and bridge load analysis problem noting that errors may exist in the clearance data, location or route.
• Manually modify your trip by dragging any segment and moving it to an alternate route, and then re-analyzing that new route for oversize limitations.

The directions generated by RoutePreviewer and any preliminary passing or failing indications from analysis of the proposed route (each, a “generated route”) are for planning purposes only. You may find that construction projects, road conditions, missing, unknown, or improperly located OS/OW constraints, or other events may cause your actual route to differ from the generated route. Bentley makes no guarantee that any jurisdiction located along the generated route will issue a permit for your trip and Bentley makes no guarantee that the generated route will satisfy the specifications of your vehicle and load. You must obtain all required state and local OS/OW permits and obey all signs or notices regarding your route. By using RoutePreviewer, you assume all risk of use.
