London Bridges, Tunnels, and Road Barriers with Height Restrictions

877 structures within Greater London and the M25 boundary include low bridges, tunnels, and road barriers. The Greater London Authority maintains this dataset, which is updated annually and includes height restrictions in metric and imperial units, coordinates, and borough information. Data is available in a CSV file within the platform's Roads data bucket.

Use Cases

• Route planning for high vehicles based on height restriction categories.
• Spatial analysis of infrastructure constraints using easting and northing coordinates.
• Identifying Transport for London Road Network (TLRN) areas where restrictions apply.
• Municipal asset management and maintenance scheduling based on structure type and location.

Strengths

• Covers 877 specific structures, providing a concrete count of relevant infrastructure.
• Includes both metric and imperial height restriction categories for user flexibility.
• Contains precise geospatial references including easting, northing, latitude, and longitude.
• Annual update schedule suggests a commitment to data maintenance.

Limitations

• Row count for the dataset is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to its focus on Greater London.
