The western approach

The Sorell Causeway is a causeway in Tasmania that stretches from the western side of Midway Point across Orielton Lagoon to Sorell. Together with Mcgees Bridge (that connects the eastern side of Midway Point) they connect Sorell with Hobart via the Tasman Highway.
It had been decided much earlier that if a crossing at Pitt Water could be made, it would considerably reduce the time to reach Sorell. The engineering was difficult, but with a ready supply of convict labour on hand, the causeway was constructed with main force. It was finally completed in 1872.
In recent years it has undergone massive repairs and modifications. It has been decided that there needed to be a better flow of tidal water from Pitt Water and Orielton Lagoon into the open sea as the stagnation was causing outbreaks of Blue-Green Algae which was poisoning the other marine species there. As a result, sluice conduits were cut into the lagoon, and a new pile system was created, to turn longer sections of the causeway into actual bridges.
