Lane Closures on Toowoomba Bypass and Highway Delays: Sunday Traffic Update

Major Delays on Toowoomba Bypass

Motorists using the Toowoomba Bypass (Warrego Highway) today, Sunday, March 29, 2026, should prepare for significant travel adjustments. The Department of Transport and Main Roads has confirmed that fixed lane closures remain in effect on both northbound and southbound lanes between the Warrego Highway West interchange at Charlton and the Gore Highway interchange at Athol. These closures are scheduled to operate from 6:00 am to 6:00 pm. Heavy vehicle operators must take extra care, as strict width restrictions are in place: vehicles over 3.5 metres in ground contact width or 4.0 metres in load width are required to use the approved detour via the Warrego Highway, Troys Road, and Toowoomba-Cecil Plains Road.

Safety Upgrades on Cecil Plains Road

Ongoing construction continues on the Toowoomba-Cecil Plains Road corridor between Torrington and Cecil Plains. Commuters heading west today can expect single-lane closures under controlled conditions. A reduced speed limit of 40km/h is currently in force to protect work crews as they carry out safety upgrades, including the installation of guardrails and the widening of road shoulders. Traffic controllers are on-site to manage flow, but residents are advised to allow for an additional 10 to 15 minutes of travel time through this zone.

Highfields and Local Roadworks

In the northern districts, the Highfields Road Intersections Upgrade project is resulting in long-term traffic changes. While significant new closures on Kratzke Road are scheduled to commence tomorrow, the intersections at O’Brien Road, Lauder Drive, and Rogers Drive currently feature reduced speed limits and temporary shoulder closures. Motorists are urged to follow all directional signage and remain vigilant for workers near the roadway.

Further out from the city center, Reichle Road in Yandilla remains fully closed to all traffic for flood recovery culvert replacement works. This closure is expected to remain in place through the end of the month. Detours are active via Owen’s Scrub Road, Grasstree Road, and Church Road, which may add considerable time to trips in the northern rural district.

Public Transport and Regional Alerts

For Toowoomba residents planning a trip toward Brisbane today, Translink has issued major service alerts for the South East Queensland rail network. A weekend track closure is currently affecting the inner-city and Ferny Grove lines, with rail replacement buses operating between Roma Street and Albion stations.

Furthermore, due to the "Run Army" event occurring in the Brisbane CBD this morning, railbuses will not be able to service Central station until after 10:00 am. Travelers connecting from regional services should use the replacement stops at Roma Street or Fortitude Valley to complete their journeys. On the local Toowoomba bus network, services are operating on a Sunday timetable, though commuters should monitor for potential short-notice cancellations due to regional staff availability.
