Multiple Fire and Emergency crews are responding to a scrub fire near Hanmer Springs this afternoon.

The fire broke out near State Highway 7A, the main route into Hanmer Springs, just before 2pm.

Six fire appliances are currently on the scene, along with two tankers, and two helicopters.

The blaze was about 500 metres in length and a hundred metres wide.

A Fire and Emergency spokesperson said smoke from the fire was drifting across the highway, prompting the closure of the road due to safety concerns.

The road will remain closed until the situation no longer poses a hazard to traffic.
