The truck mounted the curb and continued through the guard rail about 4.30pm, puncturing its fuel tanks and causing diesel to leak onto the road.
Deniliquin’s Fire + Rescue NSW brigade implemented HAZMAT (hazardous materials) processes, while other emergency services provided support.
Traffic returned to normal after the diesel was cleaned up, but was closed again temporarily when the tow truck arrived to remove the truck about 9.30pm.
The cause of the crash has not been officially determined, but brigade Acting Captain Les Booth said Sunday’s consistent rain may have contributed.
He said the entry to the bridge from Charlotte St can be slippery when wet, and urged motorists to proceed with caution regardless of the weather.
This is the second incident involving a truck to have required an emergency services response at the entry to the bridge in little over a week.
About 8.15pm on Saturday, May 9, a prime mover was entering the bridge from Charlotte St when a car failed to give way and crashed into its side.
Traffic was diverted around the crash site until the car could be towed.
Flat fills with smoke
The resident of an east Deniliquin unit had to be treated for smoke inhalation after a cooking fire on Saturday evening.
Emergency services were called to the unit about 5.30pm.
While the fire was contained to the oven, it did cause smoke to fill the home.
The occupant was treated at the scene by Ambulance NSW paramedics, while Deniliquin Fire + Rescue worked to ventilate the home.
