 WASHINGTON, D.C. — The U.S. Federal Highway Administration (FHWA) released a video that illustrates how to build a geosynthetic-reinforced soil integrated bridge system (GRS-IBS). It is intended to educate designers, engineers, contractors, and inspectors on the fundamentals of the GRS-IBS. The video follows the GRS-IBS Interim Implementation Guide (FHWA-HRT-11-026), available online at www.fhwa.dot.gov/publications/research/infrastructure/structures/11026.

Included in the 19 minute video is:
• explanation of GRS and its history of development;
• interviews with designers, owners, and construction personnel;
• narrated video footage to explain the construction of the three main components — reinforced soil foundation, abutment, and integrated approach; and
• time-lapse photography to show the speed of construction.
