Product Information

Accelerated Bridge Construction (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.

ABC improves:

  • Site Constructability
  • Total project delivery time
  • Work-zone safety for the traveling public

ABC reduces:

  • Traffic Impacts
  • Onsite construction time
  • Weather-related time delays

A common reason to use ABC is to reduce mobility impacts because the safety of the traveling public and the flow of the transportation network are directly impacted by onsite construction related activities.

Other common and equally viable reasons to use ABC deal with site constructability issues. Oftentimes long detours, costly use of a temporary structure, remote site locations, and limited construction periods present opportunities where the use of ABC methods can provide more practical and economical solutions to those offered if conventional construction methods were used.

AASHTO Girder

AASHTO sections are typically used for railroad, or other private entity, bridge construction when a standard wide flange (WF) girder section does not meet the project design criteria.  The top flange of AASHTO shaped girders is not as wide as standa...

Box Beam

Box Beams are typically used for 80′-118′ bridge spans. The design allows for a typical 4′ width section to include integral voids which reduce the product weight and are often used when box depth and speed of construction are part ...

Bulb I

The Bulb I (BI51, BI63 and BI75) is a less commonly used ODOT standard girder for medium to long length span bridges. It utilizes the BT section with the deck blocked in to achieve difficult site requirements such as heavy super elevations and vertic...

Bulb T

The Oregon Bulb-Tee (BT) girder is the preferred choice for most Oregon medium to long span bridges requiring a CIP deck. Bulb Tee precast/prestressed girders are typically used in spans from 60-185′ with significant loading.
