FOI003606 FOI Highways

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.
