There are approximately 550,000 bridges in this country on interstates, state highway systems and off-system roads and streets. Of these, 80 percent or more were built before 1934-45 years ago -- and an estimate of more than 200,000 are structurally deficient, functionally obsolete or just plain dangerous. The enormity of the task facing highway/bridge-builders at every level of jurisdiction can be brought into focus with a look at the Indiana situation. The Hoosier state has 100,000 bridges, a majority of which were built before 1934 and hundreds dating back to the turn of the century. More than 6,500 of the state's rural bridges are unsafe for standard school buses; 1,445 are critically substandard and should be replaced or rebuilt at once, and 8,140 require temporary repairs in order to be used safely. On the brighter side is the fact that the federal government -- the primary source of substantial funding -- has become aware of the real emergency nature of the bridge problem. With the appropriation of $900 million for 1979, together with a combined $3.3 billion for 1980-82, the first steps toward a solution have been taken.
