AccelBridge is a proprietary prefabricated bridge system designed for rapid and efficient construction. Key features include:
Match-cast prefabricated deck panels
Compressed deck design without internal post-tensioning (PT)
Compatibility with all common bridge girder systems,
including steel I-beams, steel box girders, concrete I-beams, and concrete U-beams.
ADVANTAGES OF ACCELBRIDGE
• Supreme Durability
AccelBridge features a unique detail with no rebar or PT across the joint, completely eliminating the source of joint corrosion. The match-cast joint is compressed to ensure reliable shear and moment transfer, making the deck highly durable and long-lasting.
• Simple to Construct
AccelBridge eliminates the need for cast-in-place (CIP) joints. The deck is fully supported by the girder system, allowing for easy installation. On average, deck panels can be erected in just 20 minutes with conventional construction equipment, no specialty contractors or specialized workforce required.
• Speed
For accelerated construction projects, AccelBridge has proven to deliver outstanding results. It set a record by replacing the deck of a three-span bridge on Interstate I-89 in just 59 hours—from deck removal to reopening for traffic.
• Cost-Effective
On average, AccelBridge costs $12 to $20 less per square foot compared to other precast deck systems, such as those with longitudinal post-tensioning or UHPC joints. It offers a low-cost alternative to precast segmental bridges while maintaining exceptional speed of construction.
PROJECT APPLICATIONS
AccelBridge has been successfully implemented in 10 bridges across the U.S. and Canada. Its simplicity and fast construction process make it a favorite among contractors, especially in alternative project delivery methods like General Contractor/Construction Manager (GC/CM), Value Engineering (VE), and Design-Build.
