As part of construction of stage 2A of the Canberra light rail, work will commence in 2022 to raise part of London Circuit by 6 m (20 ft) and provide a signalised, level intersection with Commonwealth Avenue. The ACT Government claim this will create a more "people oriented" space, improving access for pedestrians and cyclists as well as public transport infrastructure,[4] however warned of traffic disruption over a four year period during construction. This intersection is currently grade-separated and makes use of a cloverleaf style ramps, requiring the demolition of the current overpass, to be replaced by new roadway built on top of 60,000 m3 of fill material. Tracks will be laid along the western portion of London Circuit between this new junction and Northbourne Avenue, with a station to be built on this section to serve City West and the Australian National University. A portion of the eastern section of London Circuit between Commonwealth and Constitution Avenues will also be upgraded as part of this project.[5] These works are expected to be completed in 2024.[6][7]
