When rehab work is necessary, itmeans that there are structural deficiencies in the structure. When a bridge is ―functionallyobsolete,‖ it is time for bridge replacement. An example of a functionally obsolete bridge is onewhere the traffic has increased to such a degree that the bridge can no longer meet the demand.―A lot of factors affect bridge replacement.‖ The most important of these are usage and location.For example, bridges that are salted down in the winter decay at a faster rate. There is noconnection between bridge replacement and changes in technology; i.e. a bridge would notimmediately be replaced due to increasing technology.\15-SEP-11\\ D-3
