Integral Abutment Bridges

Integral abutment bridges provide an excellent alternative to conventional bridges built with bearings and expansion joints. Integral abutment bridges incur lower construction and maintenance costs compared to conventional bridges. In addition, they have a longer service life and a superior seismic performance compared to conventional bridges. Forty-one states are now using integral abutment bridges. Despite their wide acceptance by state transportation agencies and the engineering community in general, however, use of integral abutment bridges for long bridges and in situations that involve complex structural and soil conditions is still limited. This article presents the findings of a survey conducted in 2009 by the University of Maryland at College Park that focuses on state integral abutment bridge practices. It summarizes the responses received from the states with regard to the status of use, problems and costs associated with the use of integral abutment bridges.
