BEBO® Bridge Concrete Arch System

The BEBO Bridge Concrete Arch System is a combination of cast-in-place concrete footings, precast arch elements, headwalls, and wingwalls. The system uses the fundamentals of soil-structure interaction to achieve superior strength and stability. The results are the largest precast arch spans in the world.

Developed in 1966 in Switzerland, the BEBO Concrete Arch System is a precast concrete version of the arches used in Roman aqueducts built two millennia ago-which are still standing.

With spans from 12 to 102 feet, BEBO can be installed quickly with minimal long-term maintenance. The precise modular system offers set-in-place construction and attractive aesthetics. The system uses 3 distinct geometries - the E-series, C-series, and T-series - to ensure the optimum configuration for your site.

Benefits of the BEBO Arch System:
  • Buried Bridge Structure - Reduces maintenance costs and lowers life cycle costs as there are no bridge deck or joints at the deck/roadway interface.
  • Modular Bridge System - Rapid installation results in reduced overall project costs, delays and detours.
  • Designed “Site Specific” - Meets your site needs in full compliance with AASHTO and AREMA design standards for highway and railway use.
  • Full Scale Load Tested - Verified engineering design methodology.
  • Easy Site-Adaptability - Flexible layout options to fit within the right-of-way - curve the structure with a stream or adjust for vertical and horizontal clearance requirements.
  • Manufactured in controlled environment with standardized components - Manufacturing is fast and efficient allowing us to offer a high quality yet cost-effective bridge option.

Precast Structures for Culverts, Canals and Enclosures

Our CON/SPAN O-Series, B-Series and BEBO structures provide a total set-in-place construction solution for culverts and stream enclosures.

Precast Bridges for Pedestrian and Recreation Traffic Loads

CON/SPAN O-Series, B-Series and BEBO have been used in a variety of applications for pedestrian structures, including bike paths, ski tunnels under roadways, and golf courses. With an aesthetic appeal, these systems can provide access either over roadways or sensitive areas or under highways, even in high-fill applications.

Precast Structures for Underground Storage Structures

Underground vaults constructed with Contech’s precast concrete arch system have a proven cost advantage over alternative underground storage solutions because of their fast installation and quality production. Designed for highway loading above the structure, CON/SPAN vaults will stand the test of time.

Precast Structures for Wine Cellars and Caves

Underground vaults constructed with Contech’s precast concrete arch system can be utilized to create a wine cellars or caves. CON/SPAN offers classic cave designs using modern techniques. Underground vaults for wineries constructed with the CON/SPAN system provide many of the advantages of traditional cellars or natural wine caves. The great flexibility of the system allows earthen floors, multiple vaults placed side by side, and units that can be furnished with optional endwalls and headwalls.

Precast Bridges for Bridge Replacement

For bridge replacement or Design Build projects, our Precast bridge systems can substantially reduce design and construction time, improve safety and ensure quality components for long-term performance.

Precast Structures for Bridge Rehabilitation

CON/SPAN O-Series, B-Series and BEBO bridge structures can cost-effectively and quickly be installed to support concrete bridges that exhibit deterioration in the concrete superstructure and upper portions of the abutments - utilizing the existing foundation. In most cases, in a single day, the bridge arches can be positioned leaving the existing beam bridge and abutments in place.

Precast Bridges for Stream and Wetland Crossings

When environmental factors are a consideration, CON/SPAN O-Series and B-Series provide a natural choice because they offer clear spans from 12 to 65 feet with small footprints that minimize intrusion into natural areas. BEBO offers strength and stability, resulting in the largest precast arch spans available, allowing minimal impact to natural areas.

Precast Bridges and Structures for Grade Separation

Our CON/SPAN and BEBO structures are commonly used for grade separations. These systems are strong enough to carry massive off-highway and railroad loads and are available in shapes to accommodate critical clearance boxes.

Precast Structures for Mining Portals, Rail Tunnels and Conveyor Enclosures

Our durable CON/SPAN and BEBO structures can meet heavy duty demands for industrial or mining applications. CON/SPAN and BEBO structures can be adapted for use in tunnel applications or improving mine entrances. The arch shape is also ideal for supporting aggregate piles and can be designed to accommodate site specific openings and equipment requirements. Underpasses and overpasses can be designed using Cooper E-80 loading, and these prefabricated systems allow for fast installation and easily accommodate staged construction methods for busy, active railroad tracks.

Precast Bridges for Heavy Loading Applications

CON/SPAN O-Series, B-Series and BEBO structures can easily accommodate Heavy Equipment Transport (HET) loading and maintenance requirements and set-in-place installation makes them a great solution for stream crossings.

Precast Structures for Taxiway Bridges and Runway Extensions

Specifying CON/SPAN and BEBO bridges and underground structures for airport applications offers a number of advantages for airport designers. Fast installation shortens work schedules and disruptions, while the large load-carrying capacity of their arch is perfectly suited for high-load airport applications. CON/SPAN bridges have been used for airport taxiway underpasses and overpasses (easily bearing 747s, Antanov 225, and other heavy aircraft), runway extensions, as well as glycol storage tanks for de-icing solvents and tunnels for baggage tugs.
