Katherine Town Council says the work is scheduled to be finished by 1pm.

The repairs are to the approaches to the single land crossing and will themselves be constrained to one lane.

"Please adhere to all signage and traffic controllers," council said in a statement yesterday.

"Council appreciates your cooperation and apologises for any inconvenience this may cause."
