Forterra has a full line of precast modular bridge systems that allow you to cost-effectively build new bridges in a fraction of the time that traditional techniques require. Precast modular bridge systems are also an efficient choice for replacing existing bridges that have become unsafe due to aging or other environmental factors. Forterra spans can be combined with available substructures to create an unlimited range of lengths, widths and styles for a wide variety of applications.

And with components like precast pier or pile caps, deck panels, barrier rails and abutment walls, the possibilities are endless. Precast Modular Bridges are used in accelerated bridge construction (ABC). ABC is bridge construction that uses innovative planning, design, materials, and construction methods in a safe and cost-effective manner to reduce the onsite construction time that occurs when building new bridges or replacing and rehabilitating existing bridges.


Precast Modular Bridge Systems can be used for the following types of jobs:

• Vehicular Bridges
• Pedestrian Bridges
• Utility Lines Support
• Temporary Bridges for Maintenance of Traffic
• Docks and Piers
• Parking Structures


Available sizes include 19’, 20’, 24’, 31’, 32’, 34’ and 40’ span lengths, with 3’6” panel widths. Please note that not all spans are available at all facilities. Contact your local Forterra sales office for sizes available in your area.
