A 10-kilometre stretch of Hume Highway in Broadford, central Victoria, literally went into meltdown as temperatures surged into the 30s, with even hotter conditions predicted over the weekend.
On Friday Victoria Police tweeted a message warning motorists to avoid the right-hand lane of Hume Freeway city-bound due to the melting road.
Melted tar began peeling from the road and sticking to hot car tyres, leaving a streaky mess of bitumen behind.
Emergency services are preparing for more difficult conditions in both Victoria and New South Wales, with both states bracing for temperatures that could even go into the mid-40s.
Victorian ambulance commander Paul Holman has described the conditions as “like a blast furnace” and potentially deadly.
A statewide fire ban is in place for Victoria on Saturday, while New South Wales is expected to swelter on Sunday.
