Tidal flows.
When the Hornibrook Highway bridge between Brighton (Brisbane) and Redcliffe across the wide estuary of the Pine River (North and South) closed, it was initially replaced by the bridge on the left known as the Houghton Highway. This had tidal flow lanes but in time, it became totally congested at peak times in particular and was augmented by the Ted Smout Memorial Bridge (right) in 2010. They then became one way each with three lanes.
Rather than snipping out the history of the three bridges which of course is rather large, I have appended a number of links below.
In this photo though you will notice that the Houghton Highway, like the Hornibrook before hand has bumps, two in fact across the two channels in the estuary to allow small craft to pass underneath. The Ted Smout bridge does not, it is built at a higher level in its entirety, reputed to be above tsunami height. The bridges are both approximately 2.7 kilometres long and the lamps have been designed to deter Pelicans from resting on them. Losing sight of the road in front because of a large white splat at 80 kph is not a happy event!
This shot is taken from the Brighton end.
