Canberra’s long-awaited Light Rail Stage 2B project is taking a major step forward as the ACT government unveils new details about its plan to overhaul key infrastructure in the city. The new vision, which was released as part of the draft Environmental Impact Statement (EIS), outlines the redevelopment of a major roundabout, aiming to connect the light rail from Gungahlin to Woden. This ambitious project will reshape the way the city operates and how residents and travelers get around.

The Stage 2B expansion will take the light rail across Lake Burley Griffin and all the way to Woden, creating a vital connection to Canberra’s city center. One of the most notable elements of this plan is the redevelopment of the Woden roundabout, a critical intersection that will be transformed to accommodate the expanding light rail network. The government has also included plans for a tunnel passing under State Circle and near the iconic Parliament House, marking a significant shift in the city’s transportation infrastructure.

At the heart of the Stage 2B expansion is the plan to revamp the Woden roundabout, which has long been a focal point for traffic congestion. The new vision details how the roundabout will be transformed into a major intersection, with new traffic lights installed to allow the smooth passage of both vehicles and the light rail. This adjustment is expected to greatly improve traffic flow while reducing congestion in the area.

Southbound traffic from the roundabout will be directed onto Yamba Drive, with drivers able to continue to Melrose Drive if needed. Meanwhile, northbound traffic from Yamba Drive will have to stop at traffic lights before continuing toward Yarra Glen. This new configuration aims to balance both the needs of vehicular traffic and the requirements of the light rail system.

The ACT government has been careful to balance technical expertise with community feedback throughout the planning process. As part of the Environmental Impact Statement, the government assessed two possible alignments for the light rail: the State Circle East option and the National Triangle Barton option. After reviewing studies and technical reports, the State Circle East alignment emerged as the preferred choice. This route is seen as more direct and will travel from Commonwealth Avenue, along State Circle, and continue onto Adelaide Avenue.

The National Triangle Barton alignment, an alternative option, would have taken a longer route, traveling along King George Terrace, Macquarie Street, and National Circuit. However, due to the nature of the project, the government is keen to explore all possibilities. As the statement notes, “The scale of the project requires a thorough assessment of available route options.” Following a comprehensive consultation process with the community and stakeholders, the draft EIS now provides a fresh opportunity for public input before finalizing the plans.

The newly released vision reveals several key infrastructural improvements that will enhance the overall experience for residents and travelers. One of the most prominent features is the planned tunnel near Parliament House. The tunnel is expected to help address engineering challenges posed by a tight bend in the light rail’s proposed route under Commonwealth Avenue. According to government sources, the cut-and-cover tunnel would begin near the median on Commonwealth Avenue before passing beneath the street and re-emerging onto State Circle.

In addition to the tunnel, the plans include a new pedestrian bridge and improvements to lighting around the Phillip Oval stop. These upgrades aim to make the area more accessible and safer for travelers and commuters using the light rail system.

Travelers and commuters in Canberra are likely to experience a significant change once Stage 2B is completed. The light rail extension will create a seamless connection between the city center, Lake Burley Griffin, and Woden, making it easier for people to travel across the city quickly and efficiently. For those who rely on public transport, the new light rail line is expected to cut down travel times and reduce reliance on car travel.

However, during the construction phase, travelers should be prepared for some disruptions. The construction of the tunnel, as well as the redevelopment of the Woden roundabout, will require road closures and detours. It’s essential for travelers to stay updated on construction schedules and alternative transport options, especially if you’re planning to visit the area regularly.

The ACT government’s Light Rail Stage 2B project is a transformative initiative that will significantly impact how residents and visitors travel throughout the city. With improved traffic flow, new infrastructure, and a more connected public transport system, Stage 2B is poised to make Canberra more accessible and sustainable for years to come.

While there will be disruptions and construction during the development process, the end product will be worth waiting for. Once finished, the extended light rail system will be a cornerstone of the city’s infrastructure, improving both the commute for inner-city residents and tourists’ overall experience. The ultimate creation will keep Canberra a contemporary, cosmopolitan city, capable of handling the transportation demands of its expanding citizenry.
