A group of Darwin-bound truck drivers have been stranded in Fitzroy Crossing, after the Great Northern Highway was cut by floodwaters yesterday.
The Fitzroy River dropped this afternoon to 7.18 metres, allowing four-wheel-drives and high-clearance trucks to cross.
Roadhouse worker Richard Omen says around 20 trucks were waiting to cross the flooded road since Sunday.
"Most of them are heading to Darwin, through Katherine, with deliveries," he said.
"I'm not sure what kind of product they're transporting, but there are quite a few which are stuck.
"A lot of them are refrigerated trucks."
Mr Omen says the local supermarket has done well selling foods to locals looking to stock up on supplies.
"I don't think we're going to starve to death if it lasts the week or so, but a lot of the locals have bought up quite big," he said.
"A few of the local boys who've talked to me over the last few days have said on the sly to me, 'oh you know you might want to go and buy up'."
"Because they usually predict when the weather's like this and the river coming up, that we might get closed off for a month."
