Rapid Bridge Replacement Techniques
The destruction of the World Trade Center building in September of 2001 exposed the
vulnerability of domestic structures and facilities to terrorist attack. With transportation
facilities on the list of potential targets, state DOTs initiated efforts to lessen
the probability of an attack and to lessen the impact should such an attack occur.
This project initially focused on the nation's bridges and sought to lessen the impact
on an attack through rapid recovery operations by advanced planning and preparation,
which includes the development of emergency response procedures and identification
of rapid bridge replacement and repair techniques and materials. The scope of the
project was later expanded to recovery operations following any extreme event; natural,
accidental, or terrorist-planned. Chapter 2 identifies and summarizes rapid bridge
replacement and repair materials and techniques for bridge superstructures, decks,
substructures, and general elements or members as well as floating bridges and contractor
and construction techniques and methods. Chapter 3 identifies and summarizes 26 real-world
cases of rapid bridge replacements. A summary of lessons learned is also provided.
Chapter 4 addresses the effectiveness of incentive clauses in shortening construction
schedules. Chapter 5 addresses pre-event preparations and includes the evaluation
of critical bridge assets and the development of Emergency Response Plans for those
