The end is in sight to the closure of Terania St

Terania Street has been closed between Tweed and Peate streets since February 7 this year when an overheight vehicle struck the rail-over-road bridge above the road.

Transport for NSW North Region Director, Anna Zycki, said Transport for NSW engineers have been working to design temporary measures to prevent oversize vehicles from using the street and striking the disused rail-over-road bridge.

"We'd like to thank residents and businesses affected by this road closure," Ms Zycki said.

"Specialist engineers have been working to design traffic management measures to prevent future strikes, including traffic calming treatments to slow down light vehicles and restrict heavy vehicle access to Terania Street."

Transport for NSW will implement these measures in the coming weeks, including speed humps, a reduced 25km/h speed limit, restricting the lane width, installing traffic islands and surveillance camera to monitor vehicle compliance on the east and west approaches to the bridge.

Ms Zycki said the temporary traffic islands will restrict all vehicles weighing more than 4.5 tonnes from entering the restricted road approaching the rail bridge.

"There will also be new 'No right turn' restrictions entering and exiting Peate Street," she said.

"A detour for heavy vehicles is available via Wilson Street, Elliott Road and Ballina Road. Residents wishing to enter or exit Peate Street would need to detour via Pine, Crane and Tweed streets.

"Transport for NSW has received approval from the NSW Heritage Council to remove the Terania Street rail bridge and is working through the heritage approval consent conditions to enable works to proceed."
