Major Commonwealth Avenue Closure Tonight: Evening Detours and Weekend Impacts

Morning Commute Overview

Good morning, Canberra. As we wrap up the work week this Friday, 27 March 2026, commuters can expect a relatively standard morning peak across most of the territory. However, the calm start to the day belies a significant disruption scheduled for this evening that will fundamentally change how residents navigate the city center over the coming days.

CRITICAL ALERT: Commonwealth Avenue Full Closure

The headline for today’s traffic update is the scheduled full closure of Commonwealth Avenue in both directions. Starting from 8:00 PM tonight, Friday, 27 March, the road will be completely shut between the Parkes Way on/off ramps and Vernon Circle. This closure is necessary for critical Light Rail Stage 2A construction and track slab installation.

• Duration: From 8:00 PM tonight until 5:00 AM Monday, 30 March.
• Impact: No through-traffic will be permitted. Motorists heading north or south through the city must divert.
• Detours: Road users are encouraged to use Kings Avenue Bridge or the Tuggeranong Parkway as primary alternatives. Signage is in place to guide drivers through the Parkes Way interchanges.
• Local Access: The Albert Street (East) entry remains closed until 6:00 AM tomorrow, Saturday, 28 March.

City Center and Suburban Roadworks

Beyond the major artery closure, several other projects continue to impact local travel times:

• Bunda Street: The closure between Genge Street and Scotts Crossing remains in effect for the Garema Place Hotel upgrades. Pedestrian access is maintained, but drivers should avoid the area.
• Monaro Highway: Construction continues at the Lanyon Drive interchange. Expect the highway to be reduced to a single lane in each direction during off-peak hours today. Traffic lights are active at the intersection for northbound motorists; please allow an extra 10 minutes for your trip toward the city.
• London Circuit: While accelerated works have moved some fencing, London Circuit remains a heavy construction zone. Access is limited as crews prepare for the eventual partial reopening of the eastern section later this year.

Public Transport and Bus Alerts

Transport Canberra has issued several alerts for Friday commuters. Due to infrastructure upgrades and the aforementioned road closures, several stops are currently out of service:

• Bus Stop 3288: This stop remains closed today, with services expected to resume following the completion of utility works this evening.
• Bus Stop 1279: This stop remains closed through the end of the month. Passengers should check the journey planner for the nearest alternative.
• Route Diversions: From 8:00 PM tonight, all bus routes usually traversing Commonwealth Avenue will be diverted via Kings Avenue. Expect delays on the R2, R4, R5, and R6 services during this transition.

Lead Editor’s Advice

If you are planning to stay in the city for Friday night drinks or late-night shopping, we strongly recommend leaving before the 8:00 PM cutoff or parking outside the immediate construction zone. The shift in traffic flow tonight will be significant, and early congestion on detour routes like Constitution Avenue and Parkes Way is highly likely. Stay safe and plan your weekend travel accordingly.
