We are requesting your latest spatial dataset for road restrictions to support commercial driver safety.
Please provide your current dataset for:
• Bridge Height Restrictions (Physical clearances under 16'6" / 5.03m)
Preferred Format: CSV, XLSX, or Spatial GIS layer (GeoJSON, SHP, KML) containing:
• Bridge/Structure Name & Location Description
• Height Restriction (Imperial feet/inches and/or Metric meters)
• Geo-coordinates (Latitude/Longitude or OS Easting/Northing)
• Date of last physical survey or TRO revision
Less important is:
• Weight & Width Restrictions (Enforced structural or environmental limits)
• Same details
If this data is published on an open data portal or Web Feature Service (WFS), please reply with the direct link as this also might be useful.
I am also now aware of D-TRO's being centralised onto the DOT, which includes changes to signed bridge heights.
If this is a method you use, that would be useful to know.
