Gunnedah's first 24-hour petrol station catering for B-double trucks and road trains will open in September.
Trucks up to 36.5 metres in length will be able to access the 8500-square metre site opposite the saleyards on the Kamilaroi Highway.
The site will feature a Shell outlet and convenience store, 24-hour cafe, and 24-hour Burger Edge store with drive-through, and employ about 30 full-time and part-time employees.
The build is overseen by business and technology consulting practice Terra Firma and spokesperson Paul Hoare said the project was three months into a nine-month schedule.
"Fuel tanks have been installed, over 50 per cent of concrete laid and structure is just about complete," he said.
Mr Hoare said it would be the first site in the Gunnedah area with the ability to service large road trains.
"Shell asked us to find a site in Gunnedah to build a state-of-the-art facility as it is clearly lacking in the area and with the bypass plans for the township, this site opposite the sale yards was considered a prime location and there is no other site in Gunnedah to cater for large B-doubles up to 36.5 m length," he told the NVI.
The facility is expected to be completed in mid-to-late September.
