Document Type: Feature article


The author describes the temporary bridge developed by Caltrans for use in emergency situations where stretches of highway bridge are damaged. The bridge is made of salvaged railroad flatcars welded together in such a way that the bridge is modular and can be used to inexpensively and quickly bridge gaps in every structure ranging from single-lane to multi-lane highway bridges. The bridge is reusable, and can be easily transported. Finally, the author describes how the bridge functioned in its first field test during the recent spring floods in California.
