The Victoria Park Tunnel project was completed in early 2012 having been opened earlier in the year. Three northbound lanes were constructed in a cut-and-cover tunnel next to the existing four-lane viaduct. The viaduct, previously two lanes in each direction, was reconfigured to two pairs of southbound lanes; one pair accessing the Cook Street off-ramp and Port and Northwestern Motorway connections, the other connecting to the Southern Motorway. In addition to the tunnel a movable median barrier on the northbound section between the tunnel and the Harbour Bridge allows five northbound lanes to be used in peak traffic times. The southbound section was also widened to five lanes, this being permanent.
