Rapid bridge replacement or accelerated bridge construction (ABC) is a technique that allows bridges to be replaced with minimum disruption to traffic. The replacement bridge is constructed on a site near the bridge to be replaced. When it is completed, the old bridge is cut away and removed using self-propelled modular transporters (SPMTs).
American Bridge Company was founded in April 1900, when J.P. Morgan & Co. led a consolidation of 28 of the largest U.S. steel fabricators and constructors. [2] The company's roots extend to the late 1860s, when one of the consolidated firms, Keystone Bridge Company , built the Eads Bridge at St. Louis , the first steel bridge over the ...
A movable scaffolding system (MSS) is a special-purpose self-launching form used in bridge construction, specifically prestressed concrete bridges with segments or spans that are cast in place. The movable scaffolding system is used to support a form while the concrete is cured; once the segment is complete, the scaffold and forms are moved to ...
A bridge management system (BMS) is a set of methodologies and procedures for managing information about bridges. Such system is capable of document and process data along the entire life cycle of the structure steps: project design, construction, monitoring, maintenance and end of operation. [1] [2]
Underslung (lower-beam) launching gantry used for Skyline guideway construction (2015). A launching gantry (also called bridge building crane, and bridge-building machine) is a special-purpose mobile gantry crane used in bridge construction, specifically segmental bridges that use precast box girder bridge segments or precast girders in highway and high-speed rail bridge construction projects.

The patent of this wire-based system was registered in 1954 and Vorspann System Losinger was created to help develop this activity. The patent was first applied in 1956 for the construction of the Pont des Cygnes bridge in Yverdon, Switzerland. In 1966, VSL launched its strand post-tensioning system.
It uses the same modular components as the Close Support Bridges. A standard bridge set is carried, launched and recovered from 3 specialist vehicles (1 x Automotive Bridge Launching Equipment (ABLE) and 2 x Bridging Vehicles (BV). Up to 44m of bridge can be built using this system, although only 32m is possible with the 3 vehicle combination.
