A TRUCK carrying an excavator northbound on Southern Cross Drive at Zetland collided with the Eastern Distributor Tunnel after the driver mistakenly believed the boom of the excavator was low enough.
New South Wales Police Force Traffic and Highway Patrol Command said the boom of the excavator crashed into the tunnel at about 9.10am, causing minor damage to the tunnel and extensive damage to the excavator.
Police said the impact also caused two large excavator buckets to dislodge from the load and land on the roadway.
The driver, a 57-year-old man from Glenmore Park, observed height signs indicating 4.4m.
Roads and Maritime Services Heavy Vehicle Inspectors, along with police, attended the scene where the now damaged and lower height of the boom was measured to be 4.58m.
The driver was issued penalty notices for disobey low clearance sign - tunnel, drive heavy vehicle fail to comply with dimension requirements - substantial risk, and drive heavy vehicle not comply loading requirements - substantial risk.
Roads and Maritime Services are conducting further investigations where further registration action may be taken.
Traffic was heavily affected where the roadway was cleared of debris and the truck was assisted in reversing from the tunnel.
