With works continuing as part of the Bremer River Bridge remediation, access has been extended for OSOM (over size, over mass) vehicles at Cunninghams Gap.
The Bremer River Bridge project includes critical rehabilitation and strengthening repair works, including bridge re-decking, to extend the life of the existing westbound bridge structure.
The westbound steel girder bridge has been operational since January 1958 and supports around 30,000 westbound vehicles per day, with just over 4000 of these being heavy vehicles.
Transport and Main Roads (TMR) advises that the current conditions of operation will continue for heavy vehicles on the Cunningham Highway travelling through the project site at Cunninghams Gap (between Tregony and Mount Edwards) until June 30, 2025.
“Temporary short duration increased conditions of operation restrictions may apply after 30 June 2025 to OSOM movements, which if required will be communicated with notice (2 weeks),” TMR added.
OSOM vehicles operating under an NHVR issued Permit (greater than 4.5m width) are only permitted access between 8:00pm – 5:00am (night travel only). To apply for a permit, please visit the NHVR portal.
Vehicle dimensions permitted to pass through the roadworks site are:
- Max. vehicle width: 4.5m (ground contact)
- Max. load width: 7.5m (load must be able to clear 1.2m above ground)
- Max. length: 60.0m (including block trucks)
- Vehicles wider than 7.5m are not eligible for consideration.
OSOM vehicles travelling under exemption:
- Must contact the project’s traffic control on UHF CH 40 when approaching the site.
- Shall be required to stop and hold in a designated OSOM holding bay until released by traffic control to travel through the site.
- Vehicles that are 3.1m or less in width shall not be allowed to traverse the site at night.
- Vehicles wider than 3.1m shall be required to traverse the site prior to sundown.
TMR added, “Traffic conditions at the Cunninghams Gap roadworks site are frequently changing. Operators must ensure they have adequately assessed the site within seven business days prior to their travel to ensure road conditions are suitable for their intended passage.”
