There will be an upcoming full bridge closure on this section of the Gwydir Highway, with extended diversions in place for vehicles over 4.5 tonne.
Jackadgery Bridge on the Gwydir Highway will close from 11am Saturday May 31 to 12pm Sunday June 1.
The bridge will reopen at 8am on Sunday June 1 to light vehicles only. Heavy vehicles over 4.5 tonnes will need to wait until 12pm on Sunday June 1 to access the bridge.
Transport for NSW (TfNSW) says the bridge closure is part of ongoing essential bridge maintenance work that started in late-January 2025.
The full closure will allow for concrete to cure and reach minimum strength before vehicles can pass. Access for emergency services will remain.
Detours
Light vehicles travelling north can use Summerland Way, Bruxner Hwy to New England Hwy. Light vehicles travelling south can use Pacific Highway, Waterfall Way to New England Highway.
TfNSW says all vehicles, including freight operators and OSOM, should plan their trip in advance outside of these closure times as detour routes will be significant.
Detour routes via minor roads are possible, however it may not be appropriate for OSOM or larger vehicles.
When the bridge reopens to all vehicles at 12pm Sunday June 1, it will operate under single lane closures with alternating stop/slow arrangements and a 40km/h speed limit.
