SUNSHINE Coast Local Disaster Management Co-ordinator Alan Rogers said the Bruce Highway will be closed at Kybong for traffic heading north to Gympie for the next 24 hours.
"There is also no access for heavy vehicles or cars to Gympie via Kin Kin," Mr Rogers said.
"Six Mile Creek is over roads at Cooran and Kin Kin which is preventing vehicular access from Pomona northbound into Kin Kin.
"Heavy vehicle drivers, travellers and visitors to the region will not be able to get through to Gympie and will need to make alternative travel arrangements.
"An evacuation centre is open at Nambour Civic Centre, 60-64 Currie St, Nambour. For more information call council's customer contact centre on 5475 7272.
"Importantly, remember, if it's flooded - forget it."
