U.S. Landmarks: Handle With Care
Landmarks are treated with kid gloves during restoration, but striking a balance between costs and aesthetics is difficult. In addition to structural integrity, original construction methods...
Replacing Bridge Decks
U.S. bridges last an average of 68 years, their decks 35 years. But few bridges have been built with provisions for future deck repair, the only criterion being lowest first cost. During...
Bridges on Screen
Computer software can help engineers produce designs for more economical, constructable bridges in less time than conventional methods. Software is being put to work in bridge design departments...
Bumpy Road Ahead
By 1999, we will be riding on highways and public transit paid for by the 1991 reauthorization of the National Surface Transportation Act. Or maybe we won't. The new bill,...
