The first modular bridge system to be discussed is the Inverset™ system produced by the company Amcrete Products, Inc. In this bridge system, a section, consisting of the superstructure and the decking surface, is cast upside-down suspended from wide flange steel girders. This method causes a prestressing effect in the steel girders, and when the section is turned upright for placement, the deck is already in a compression state.
Inverset™ Bridge Systems are used as a combination of the superstructure and decking system of the bridge. It is connected to the bridge substructure on-site.
The bridge modules are transported to the site completely fabricated. Once on site, the sections are installed onto the substructure.
