Is information on railroad bridge inspections included in the NBI?
Some bridges carrying highway traffic are owned by railroads. For instance, a public road that crosses railroad tracks may be owned by the railroad if built within the railroad right-of-way. Ownership in these cases depends on the agreements made between the political jurisdiction and the railroad. There are a small number of railroad-owned highway bridges in excess of 6 meters in total length in the inventory: 1,016 nationally. Bridges carrying railroads are not included in the database unless they also carry a public road or cross a public road where information of certain features, such as vertical or horizontal clearances, is required for management of the highway system.
