Repair works on the Mt Crosby Road overpass over the Warrego Highway are continuing, with closures, detours and changed traffic conditions affecting travel through the Mt Crosby area.
A Bridge Strike That Triggered Repairs
The Mount Crosby Road overpass at Karalee was damaged in mid-2025 after being hit by an oversize truck. The repair program was set up to remove and replace damaged bridge girders, followed by restoration of the road deck and footpath.
The incident was also reported as involving a truck carrying a wind turbine tower, with the strike occurring in May 2025. Ongoing works have been staged to manage traffic while structural repairs progress.
The Intensive Weekend On The Warrego Highway
Transport and Main Roads scheduled an intensive works period from 8 p.m. Friday 16 January 2026 to 5 a.m. Monday 19 January 2026 to lift out and replace damaged girders using a large crane.
During that period, the Warrego Highway was fully closed westbound, eastbound traffic was reduced to one lane, and the Mount Crosby Road overpass was closed in both directions.
Detours And Travel Time Impacts
Detours were set via nearby interchanges, with northbound overpass traffic directed via the Warrego Highway westbound to return through the Kholo Road interchange. Southbound overpass traffic was directed via the Warrego Highway eastbound to return through the River Road interchange.
Transport and Main Roads advised motorists to expect peak-time delays during the intensive works period and to plan trips ahead, with traffic control and temporary signage in place.
Reopening, Speed Limits And Heavy Vehicles
After the girder replacement, the overpass reopened at 5 a.m. Wednesday, earlier than the previously advised closure period that extended to Saturday 24 January 2026.
With the key structural work completed, heavy vehicles were able to use the overpass again and earlier loading restrictions were removed. A 20 km/h speed restriction remained in place while further restoration continued.
Night Works Through To April 2026
Remaining works include reinstating the footpath, bridge deck, road surface and barriers, along with restoring lane alignment. These tasks are planned to be completed at night to limit disruption, with typical hours listed as 8 p.m. to 5 a.m., Sunday to Friday, conditions permitting.
During parts of the program, the overpass is expected to operate under traffic control with alternating flow at night. Westbound closures beneath the overpass are also scheduled during night works, with traffic detoured via the Mount Crosby Road interchange exit and entry ramps.
The works are expected to be completed in April 2026.
What People Are Saying Online
Comments posted on social media have raised concerns about congestion, travel delays and detour arrangements during the closures. Some posts also shared route suggestions for drivers travelling to and from nearby interchanges.
