There has not been a great deal of interest in the design and construction of semi-integral abutment bridges since. The reasons for not attempting more designs of this type are not well documented. It could be attributed to the improved quality of expansion joint systems becoming available to designers or the absence of rational design methods, construction procedures or performance data
