The South Australian Department for Infrastructure and Transport (DIT) is upgrading a culvert on the Horrocks Highway, two kilometres north of Rhynie to improve freight productivity and safety.
DIT says this $4 million upgrade is another step towards this section of the Horrocks Highway being able to accommodate larger heavy vehicles, including road trains up to 36.5 metres in length.
Culverts enable water flow underneath road, preventing flooding, soil erosion and damage to the highway, making safer drives during severe weather events.
Early works began on Thursday February 6 and will operate from Monday to Friday between the hours of 7am to 5pm until early March 2025. Some Saturday work may be required. During this time, a temporary access track will be built at the worksite.
Following this, major works will begin, and traffic will be reduced to a single lane and diverted around the worksite via the temporary access track. The project is expected to be completed in July 2025.
Over 1800 vehicles travel along this section of highway each day, including 230 heavy vehicles.
“This culvert upgrade will help the Horrocks Highway support larger heavy vehicles, making freight transport more efficient and improving safety for all motorists in the region,” a DIT spokesperson said.
“We appreciate the patience of local drivers while these works get underway, and every effort will be made to minimise disruptions.”
