Material Usage and Condition of Existing Bridges in the U.S.

Data on the market share of the four major bridge construction materials used in the US (reinforced concrete, prestressed concrete, structural steel, and timber) are summarized in this report. All bridges carrying public roadways are considered. Data are extracted from the National Bridge Inventory (NBI) as of December 2003. The NBI is maintained by the Federal Highway Administration (FHWA). Tables and figures present information on both the number and deck area of existing bridges. To focus on current trends, data are also presented for bridges built during 1999-2003. The market share and performance (structural deficiency) of bridge materials are given by year of construction. This report updates data published in a similar document in September 2001.
