The Riverside Expressway is part of the Pacific Motorway that runs through Brisbane, Queensland, Australia. It is located on the western side of the Brisbane CBD and is made up of various bridges and overpasses. The North Bank development is proposed to alleviate the visual disruption of the expressway and recapture Brisbane for pedestrians. The Expressway runs the entire western length of the Brisbane CBD from Coronation Drive to the Captain Cook Bridge at Gardens Point, an estimated before becoming the Pacific Motorway which ends at the Gold Coast. The roadway has been described as a concrete barrier on the river's edge and an eyesore, however others have praised the dramatic and visually arresting views of the Brisbane River, city skyline and surrounds experienced by drivers and passengers on the elevated expressway. Congestion Traffic congestion in the central city area became problematic in the late 1950s and 1960s. The Story Bridge, William Jolly Bridge and Victoria Bridge were clogged with traffic wanting to cross from one side of town to the other. A traffic engineering company called Wilbur Smith and Associates was asked to study Brisbane's traffic problems by the state government. They delivered a report, the Brisbane Transportation Study, which included plans for traffic management for many years. In 2016, the road was the most congested in the state with average traffic speeds in afternoon peak times slowing to 19 km per hour. History Construction on the Riverside Expressway began in late 1968, when the pylons for the bridge were laid on the north bank of the Brisbane River. It was built over the former Short Street which provided access to a wharf. The bridge was completed in 1975 as was the Southeast Freeway to Holland Park. The Brisbane River was used as a source for gravel to make much of the concrete used in construction. The freeway was opened on 22 July 1976 by Governor Sir Colin Hannah. The development of the Expressway necessitated an increase in Turbot Street's capacity as an arterial road, so the street was widened. In 2018, a three car accident at Greenslopes caused around a 10 km traffic delay including the whole of the Riverside Expressway. In February 2021, Extinction Rebellion staged a protest on the roadway at the Turbot Street offramp. 2006 appearance of cracks During September and October 2006, roadworks occurred on the Expressway, and surrounding structures, including the Captain Cook
