The **Sorell Causeway** is a [causeway](/source/Causeway) that carries the [Tasman Highway](/source/Tasman_Highway) across [Pitt Water-Orielton Lagoon](/source/Orielton_Lagoon), from the western side of [Midway Point](/source/Midway_Point%2C_Tasmania) to [Sorell](/source/Sorell%2C_Tasmania) in the south-east of [Tasmania](/source/Tasmania), Australia. The causeway and adjacent [McGees Bridge](/source/McGees_Bridge) provide vital links between Hobart and two of Tasmania's principal tourist attractions - [Port Arthur Historic Site](/source/Port_Arthur%2C_Tasmania) on the [Tasman Peninsula](/source/Tasman_Peninsula) and the picturesque East Coast via the Tasman Highway.

## History

In colonial times, the [Richmond Bridge](/source/Richmond_Bridge%2C_Tasmania) had been the primary crossing point of the [Coal River](/source/Coal_River_(Tasmania)) on the road from [Hobart](/source/Hobart) to [Sorell](/source/Sorell%2C_Tasmania) and beyond to the [Tasman Peninsula](/source/Tasman_Peninsula) and [Port Arthur](/source/Port_Arthur%2C_Tasmania).

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.[1] 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.[2]

The Sorell Causeway is the second such convict-built causeway in the South-East of Tasmania, and is similar to the causeway section of the former [Bridgewater Bridge](/source/Bridgewater_Bridge#Fourth_bridge) across the [River Derwent](/source/River_Derwent_(Tasmania)).

## Description

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](/source/Cyanobacteria) 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.

Ever since its construction it has been a major route of access from Hobart to the east coast and the [Tasman Peninsula](/source/Tasman_Peninsula), and is now a section of the [Tasman Highway](/source/Tasman_Highway).
