Granor expansion joints at Dynon Road Interchange

The elevated “T” shaped bridge structure over passes critical Port access rail lines. Three differing types of Granor supplied Expansion Joints were used on these structures, each with differing capacities and features

At the abutments and the immediate spans where smaller movements occurred the Granor XJS® composite joint and the Granor Ausflex® AC-AR stripseal systems were used.

Larger mid-span joint locations that provided for larger movements necessitated the use of 180 metres of Granor ETIC® saw tooth cast aluminium Finger joints. Models EJ-110, EJ-160 and EJ-250, with movement capacities of 110mm, 160mm and 250mm total respectively were adopted in the Bridge design.

The Granor ETIC® EJ-250 model is a recent addition to this range of Finger joints and the Dynon Road interchange was the first structure in the world to use it. The Granor ETIC® “EJ” series now has joints ranging from 80mm through to 300mm total movement capacity.
