Sorell Causeway
The 928th tallest dam in the world
The Sorell Causeway is a causeway that carries the Tasman Highway across Pitt Water-Orielton Lagoon, from the western side of Midway Point to Sorell in the south-east of Tasmania, Australia. The causeway and adjacent McGees Bridge provide vital links between Hobart and two of Tasmania's principal tourist attractions - Port Arthur Historic Site on the Tasman Peninsula and the picturesque East Coast via the Tasman Highway.
