RESTRICTIONS on navigation on the River Derwent between Bridgewater/Granton and New Norfolk were lifted today, Marine and Safety Tasmania (MAST) has advised.
“Mariners are advised that the decommissioning of the old Bridgewater Bridge is complete,” a MAST spokesperson said when announcing the cancellation of Notice to Mariners M332-26 River Derwent – Old Bridgewater Bridge – Demolition.
“The prohibited area declared under M115-26 is now cancelled, and vessels can freely navigate through the area.
“Mariners are advised to navigate with caution when transiting through the new Bridgewater Bridge and past the remaining structures of the old bridge.”
A number of concrete piers from the old 1942 bridge are still in place, along with preserved elements of earlier bridges, both with in the water and on the riverbank and causeway.
Until today’s cancellation, the river has been closed at the new bridge under a Notice to Mariners, with a temporary navigation channel available for use via permit. This was to enable the safe demolition of the previous bridges and associated structures.
While the causeway remains closed on the Granton side, all fencing has been removed on the Bridgewater side and the old road has been blocked with bollards. A metal arch has been installed on that approach, framing the remnants in the river.
MAST says it is important to understand what has changed on the water. “The new bridge provides a fixed navigation opening, allowing vessels to pass underneath without waiting for bridge openings.
“If you’re cruising upstream to New Norfolk or heading back towards Hobart, make sure you understand the bridge clearance and navigation requirements before you leave.”
Before making the trip:
☑ Check your vessel’s air draft to ensure you can safely clear the bridge.
☑ Plan your passage and be aware of tides, river conditions and weather.
☑ Keep a lookout and maintain a safe speed, particularly in narrower sections of the river and familiarise yourself with the designated 5-knot area upstream of Sorell Creek.
☑ Be mindful of other river users, including paddlers, rowers and commercial vessels.
