Major Delays Expected on Commonwealth Avenue and Key Suburban Arteries This Wednesday

Morning Commute Overview

Canberra commuters should prepare for significant travel time increases this Wednesday, 18 March 2026, as several major infrastructure projects and resurfacing works coincide across the city. The most substantial impacts remain centered on the central corridor and the inner-north, with the revised 2026 bus network now fully operational to manage these disruptions.

Major Arterial Disruptions

The Commonwealth Avenue Bridge Renewal project continues to be the primary cause of congestion for north-south travel. The northbound side of the bridge remains fully closed to all traffic. Both directions of travel are currently sharing the southbound side of the bridge. Motorists are reminded that a strict 40km/h speed limit is in place through the work zone. Additionally, the Flynn Drive northbound on-ramp is restricted to Transport Canberra buses only, meaning private vehicles must find alternative routes into the city.

Construction for Light Rail Stage 2A is also affecting the surrounding area. There are intermittent lane reductions on both Commonwealth Avenue and Parkes Way as crews work on the new bridge deck. In the city center, Bunda Street remains closed to motorists between Genge Street and Scotts Crossing for ongoing upgrades, with diversions expected to stay in place until mid-April.

Suburban Roadworks and Resurfacing

Several localized projects will affect traffic flow throughout the day on Wednesday:

• Dickson: Lane closures will be in effect on Antill Street between Phillip Avenue and Cowper Street from 9:30 am to 4:00 pm for road resealing.
• Yarralumla: Expect road closures on Novar Street between Kintore Crescent and Bentham Street during the same off-peak window. Alexandrina Drive and Pescott Lane will also face lane closures for maintenance.
• Majura: The intersection of Majura Road and Fairbairn Avenue is undergoing significant upgrades. Expect closures and heavy diversions in this area through early April.
• Whitlam/Belconnen: Night works are scheduled at the intersection of William Hovell Drive and Coulter Drive from 8:00 pm to 6:00 am. This includes lane closures and side road restrictions.

Public Transport and Special Events

Commuters using public transport should refer to the 2026 revised timetable. Rapid services are maintaining 15-minute frequencies, but some local routes have been modified to account for the Commonwealth Avenue congestion. Additionally, the Canberra Balloon Spectacular is currently underway. Residents should expect heavier-than-usual traffic and increased pedestrian activity around the Parliamentary Triangle and Lake Burley Griffin during the early morning hours.

Commuter Advice

Plan for at least 15 to 20 minutes of additional travel time if your route involves crossing the lake or traveling through the city center. Peak hour congestion is expected to be heaviest between 7:30 am and 9:00 am. If possible, consider traveling outside these windows or utilizing the Park & Ride facilities to connect with the light rail or rapid bus services.
