EastLink integral abutment bridge design
On the EastLink project, which will provide a link between three major freeways and alleviate traffic congestion in Melbourne’s densely populated eastern suburbs, 23 of 71 bridges have been designed with integral abutments. Conventional abutments require the use of high maintenance ancillary items including bearings and deck joints to resist end rotations and horizontal longitudinal movements. For the integral abutments used in EastLink, the substructure is made continuous with the bridge superstructure. Rotational and longitudinal movements of the bridge deck are accommodated by flexure of the abutments and piles, forgoing the need for bearings and deck joints. The success of this design innovation is becoming more evident as Eastlink bridges are nearing construction completion, not only in cost savings, but ease of construction and ability to better deal with interfaces of road and abutment wall designs. The operator of this roadway is also looking forward to the benefits that integral abutments will have once the road is operational.
