The Hornibrook Highway Bridge was a 2.685 kilometres (1.668 mi) long timber and concrete bridge that spanned Hays Inlet and Bramble Bay between Clontarf and Brighton, linking Sandgate to Redcliffe.
It had identical rendered concrete portals at each end, and two rises along its length which permit small boats to pass underneath.

The bridge construction comprised a timber superstructure supported by reinforced concrete piers with three concrete piles of varying depths.
The superstructure had substantial round ironbark girders on corbels, with girders supporting large section ironbark and tallowwood sawn decking.
The decking was covered with coarse aggregate bitumen, and had concrete kerb edging.
At each end, the first spans of the superstructure were constructed in ribbed reinforced concrete to protect the bridge from termites and fire.

The superstructure had a slight camber that permits periodic tightening of the deck via bolt fixings along the outer girders.
The bridge had steel balustrades comprising steel stanchions supporting two circular hollow section rails and ironbark lightpoles along its length.

The portals at each end (which still exist) are finely detailed monumental Art Deco structures comprising substantial pylons spanned by a deep spandrel facing landward, and more modestly detailed rectangular frames facing bayward.
The pylons have banded rusticated bases on concrete pedestals, with central slot windows with decorative grilles on three sides, surmounted by stepped vertical elements.
The spandrel is also banded, and has a rectangular central panel with the words "Hornibrook Highway" fashioned in raised brass lettering.
The portals contain toll facilities, comprising a small office and strong room with night safe in the base of the pylons at each end.
Externally these rooms are framed by Art Deco relief patterns.
On the approach to the bridge the portals are preceded by smaller free-standing pylons either side of the road.
