Contech Con/span® O-series® Bridge
CON/SPAN® O-SERIES® BRIDGE
CON/SPAN® O-SERIES® BRIDGE
The most optimized shape in the industry. CON/SPAN’s innovative, economical design stands apart from any other system. Its distinctive arch action which utilizes fast, set-in-place construction, has been optimized, providing the ideal blend of hydraulic efficiency and structural capacity.
INFORMATION
BURIED BRIDGE STRUCTURE
Reduces maintenance costs and lowers life cycle costs as there are no bridge deck or joints at the deck/roadway interface.

BENEFITS
-Maximized clear span and clear distance between footings -Lighter piece weights or longer lay lengths for most projects. -Outward horizontal reactions – one-sided keyway, reduced forming and grouting
A LEGACY OF INNOVATIVE TECHNOLOGIES
DESIGNED “SITE SPECIFIC
Meets your site needs in full compliance with AASHTO and AREMA design standards for highway and railway use.
A LEGACY OF INNOVATIVE TECHNOLOGIES BLENDED INTO THE OPTIMIZED CON/SPAN O-SERIES
-There are over 7,000 CON/SPAN B-Series installations since 1983. CON/SPAN Bridge Systems have been used by more state DOTs than any other system. -With a history of innovation and experience, Contech has taken precast buried bridge systems to the next level with the optimization of the CON/SPAN® O-Series®. Requiring less concrete per open area than any other precast buried bridge structure, the O-Series is the ideal blend of hydraulic efficiency and structural capacity. Spans range from 12’ to 65’.

APPLICATIONS
PNTRECAST BRIDGES FOR BRIDGE REPLACEME
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 / PRESTRESS BRIDGES FOR HEAVY LOADING APPLICATIONS
CON/SPAN, BEBO, and Contech Prestress 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 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 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 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 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 STRUCTURES FOR TAXIWAY BRIDGES AND RUNWAY EXTENSIONS
Specifying precast 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.
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.
