Composite Technology for Spans Slowly Catching On

摘要

Four years after the first lightweight bridge-in-a-backpack, or BIAB, composite bridge was erected in Pittsfield, Maine, the technology is gaining traction in the U.S. and abroad, despite some learning-curve challenges. So far, BIAB has been deployed for 13 bridges in four states and, completed in May, a 26-ft span for the Trinidad Ministry of Transportation.
