It has taken four months and two previous closures, but Terania Street has reopened to light vehicles only between Tweed and Peate streets this afternoon, following the installation of temporary safety treatments.

This is celebratory news for the businesses along Terania Street and Macaulay Street after months of struggling due to lower car numbers.

Maria Butler is working at the Liberty Service Station. Maria said for owner Sharon Madden, it will feel like Christmas.

"It's been atrocious what's going on here? The trade has been so bad. She's not even covering costs. So, this is going to be bloody great."

"It's not just for Sharon and for here, it's for the whole town because this is the main road out of town. The police and ambulance needed to use this road the other day and they couldn't. An ambulance came down here and had to turn around. When I was talking to a customer later, they were working on somebody coming back from Dunoon."

"I feel for Sharon. I said to her, I get to go home and forget about it. She gets to go home and pull her hair out looking at the books. It's not good."

Now that the end is here, until the bridge is pulled down, there will be some celebrations.

"Well, I think when she's finished at six o'clock, we could end up at a local pub somewhere having a beer."

The wait for vehicles over 4.5 tonne will remain in place at the rail bridge.

A heavy vehicle detour is available via Wilson Street, Elliott Road and Ballina Road. 

Temporary ‘No Right Turn’ restrictions apply for entering and exiting Peate Street. A detour is available via Pine, Crane and Tweed streets. 

Transport for NSW thanks motorists for their patience during this time.
