Welcome to LowClearanceMap.com, the go-to resource for navigating low-clearance structures on the road. Our mission is to provide a comprehensive and user-friendly platform to help travelers avoid the hazards of low-clearance bridges and structures, ensuring a safer journey.

Our database encompasses a wide range of structures across the United States, primarily sourced from the National Bridge Inventory (NBI). While the NBI offers extensive data, it is important to note that some information may be missing or rounded. For our Canadian users, we have meticulously compiled data from various provincial websites and official documents, as a unified inventory for the entire country is currently unavailable. We are continuously working to enhance our database and welcome any contributions or updates from our users.

Key Features:

• Easy-to-Use Interface: Simply input the height of your vehicle or trailer to map all low-clearance structures along your route.
• Detailed Information: Each structure is marked with a green circle or red flag on the map, indicating its proximity to your route. Green circles represent structures within 50 miles but not directly on your route, while red flags highlight potential obstacles on your path.
• Street View Integration: For added assurance, we provide access to Google Street View, allowing you to visually verify the clearance of each structure during your planning stages.
• Continuous Updates: Our platform now supports regions in Canada, including British Columbia, Manitoba, and Quebec. We are committed to expanding our coverage and improving the accuracy of our data.

Please note that LowClearanceMap.com is not a routing application. It is designed to inform you of low-clearance structures but does not provide alternative routes to avoid them. For routing functionality, we recommend exploring other paid applications that offer this feature.
