Bridges

Exhibit 2-8 describes bridges by jurisdiction. The number of privately-owned bridges and those in rural communities declined from 1996 to 1998, but there was an increase in bridges on Federal and state property. Exhibit 2-9 relates bridge data by functional classification. The number of urban bridges—and those on arterial systems—increased between 1996 and 1998. This resulted from more aggressive reporting efforts for the National Bridge Inventory (NBI). It also occurred because many roads that included bridges were reclassified from rural to urban. Exhibit 2-10 illustrates the functional system data presented in Exhibit 2-9.
