A Northern Tasmanian walking destination famous for its birdlife, Bruno the bull and a plough in a tree is about to get a $2.4 million overhaul.
Upgrades to Tamar Island Wetlands will begin on July 6, about six months after workers removed the ageing final 150-metre section of the boardwalk.
Spreyton firm AJR Construct will have the project finished by New Year.
Parks Minister Nick Duigan said the upgrades involved replacing the two main bridges, and all of the boardwalk connecting them.
"The Tamar Island Wetlands Centre will remain open during construction, with volunteers continuing to provide interpretation and share their knowledge of the wetlands," he said.
Sections of the boardwalk will be closed while the work takes place, but visitors will be able to reach the bird hide throughout the whole project.
Stage one of the project involved removing the boardwalk that took visitors from the main island to a jetty and navigational light overlooking the Tamar.
There was once a pontoon at the end of the jetty, but it was removed after public consultation more than 10 years ago.
A government spokesperson said Parks and Wildlife had inherited the jetty and pontoon structure "many years ago".
"Since that time, the remaining structure has become unsafe and has been closed off," the spokesperson said.
"The jetty is non-functional and is not being replaced as the location is not suitable for fishing, and boat docking cannot occur there."
Tamar Island Wetlands is one of Tasmania's 60 Great Short Walks.
Meanwhile, further up the Tamar, West Tamar Council is assessing what to do with a 70-year-old bridge on Gravelly Beach Road.
The Stony Creek footbridge has been closed to foot traffic for several weeks, leaving the vehicle bridge as the only access point between the two sides of Gravelly Beach.
Council has instructed pedestrians not to cross either bridge under any circumstances.
Pedestrians wishing to travel to the northern side of the bridge can be picked up by a Manions bus outside 188 Gravelly Beach Road.
In a statement, council said engineers had determined that the pedestrian bridge had reached "the end of its practical service life".
"The assessments confirm that the primary supporting pylon has subsided, rotated from its original alignment, and exhibits significant cracking and a discernible lean," the statement read.
"Based on the engineering information, the current structure will likely require demolition. However, council is actively investigating temporary infrastructure solutions - such as a portable bailey bridge - to identify the most viable short-term option for restoring pedestrian access across Stony Creek."
