Bridges

This map service contains bridge data from the Massachusetts Department of Transportation Highway Division (MassDOT) Bridge Inspection Management System (BIMS). The data is refreshed from the BIMS database on a biweekly basis. Included in this layer are: • MassDOT and municipally-owned structures with spans greater than 20 feet. These are categorized as National Bridge Inventory (NBI) structures. MassDOT inspects NBI bridges on a biannual basis. • MassDOT Highway and municipally-owned short span bridges with spans between 10 to 20 feet. These are categorized as “BRI” structures. The first complete Inspection of the short span bridge inventory is currently in progress. • MassDOT Highway and municipally-owned Culverts with spans of 4 to 10 feet. This category is incomplete and an inventory effort is underway. Structures under Federal, other State entities or Private ownership are not contained in this layer. Also excluded are minor non-highway structures such as pedestrian and bicycle overpasses.
