It is difficult to believe, but a bus hit the Union Street Rail Bridge in South Lismore this morning, blocking the road for some time.

The Sunstate Charters bus is a Train Link bus that operates between Brisbane and Casino and Tweed Heads and Casino for the NSW Government.

The Lismore App understands the bus was not in service at the time it hit the bridge and, therefore, was not carrying any passengers.

The Richmond Police District Duty Officer said there were no injuries, and the enquiries are continuing.

It is highly likely the bus driver will be charged with traffic offences that will include a hefty fine as different rules apply for heavy vehicles.

Sunstate Charters, also called Sunstate Coaches, has been in operation for over 30 years. The office is closed today, so no one was available for comment.

Member for Lismore Janelle Saffin said what all of Lismore was thinking, "I cannot believe why drivers don't know the height of their vehicles.....seriously."

Another valid question is what the bus driver was doing driving on Union Street and heading towards North Lismore?

As for the future removal of the remaining four rail bridges, Ms Saffin said, "There are a lot of people and agencies that want these rail bridges gone. I am waiting for a written response from Lismore City Council and the SES, and then I will follow up.

"I want them looked at like Transport for NSW did for Terania Street."

On a positive note, the rail bridge suffered no damage, so Transport for NSW do not have to close it for inspection. Union Street will remain open.
