Bridges (A True Book: Engineering Wonders)

Bridges are a crucial part of trade and transportation. They allow vehicles and pedestrians alike to cross everything from rushing rivers to rocky ravines.

Readers (Grades 3-5) will trace the history of bridges from their invention in ancient times to the construction of today's engineering wonders. They will learn why different bridge shapes are suited to different purposes, how engineers choose which materials to use in bridge construction, and much more. | Katie Marsico graduated from Northwestern University and worked as an editor in reference publishing before she began writing in 2006.
