It's a show-stopping spectacle and drivers are being warned that the Burrumbuttock Hay Run could also be a traffic-stopping one.
Transport for NSW has advised people travelling in and around the Armidale area to be aware the convoy will be rolling in on Saturday.
The truckies - who all donate their time and efforts - are set to gather in Burrumbuttock in the Riverina tomorrow, then set out for Armidale the next morning.
They are due to roll into the city on Saturday, before distributing their donated hay on Australia Day from the showground.
That night, the volunteers and farmers will be treated to an "outback concert and thank you dinner".
"Traffic is expected to be heavier than usual ... as a large convoy of trucks and volunteers arrive in the area," the Live Traffic NSW statement said.
Our dawn wave of appreciation for the volunteer truckies who constitute the Burrumbuttock hay runners supplying much needed stock feed for drought and now fire effected farmers. Every little show of support is appreciated. Donate through Sydney Rotary Club. 54 trucks this run. pic.twitter.com/Q1SBJPrx6g— Margaret Hay (@Marg_Hay) January 2, 2020
"Motorists driving through the area should allow extra travel time and follow the directions of traffic controllers."
The affected areas are expected to be Glen Innes Road; and Erskine, Marsh, Taylor, Dumaresq and Kirkwood streets.
