Access change on Dogwood Creek Bridge in Qld

The heavy vehicles unit of the Department of Transport and Main Roads in Queensland has issued a change of access notice for operators using the Dogwood Creek Bridge near Miles.

From December 1, 2022, the following mass restrictions for Class 1 OSOM platforms will apply due to structural capacity limitations.

Class 1 OSOM platform combinations:

  • Must travel on the centreline of the bridge at safe operating speed (typically 30-40km/hour).
  • Must be escorted by a minimum of
    • One Level 2 Escort OR one QPS Escort in front of the combination to hold oncoming vehicles.
    • One Level 1 Pilot at the rear of the combination to ensure no other heavy vehicles are within 50m of the load as it crosses the structure.
  • Additional pilot/escorts as required for general travel on the permit must be complied with.
  • Unloaded platforms may travel in lane when safe to do so.

New applications for Class 1 OSOM loaded platforms with 8 or more axles must include a completed F4846 Load Mass Declaration form, including the following additional information:

  • The registration numbers of all modules making up the platform.
  • Calculation of the total tare mass of the platform.
  • The total loaded platform mass (includes mass of indivisible load plus tare mass of platform).

This information will provide TMR with a better understanding of the actual loading the structure is being subjected to, and will assist with the monitoring and overall management of the structure.
