    Riverside Expressway’s maintenance trial

    Motorist could experience delays when a section of Brisbane’s Riverside Expressway is jacked up this weekend in a trial run for a major maintenance program.

    Minister for Transport and Main Roads Scott Emerson said the maintenance work on the 40-year-old motorway, which carries more than 100,000 vehicles on an average workday, would ensure it continued to remain a safe lifeline for the city for decades to come.

    “During the works, a section of the expressway will be lifted about 250mm using a set of hydraulic jacks placed under the deck,” Mr Emerson said.

    “The trial lift will be conducted on one southbound span near the Margaret St off-ramp to test the system.

    “If successful, the process will be completed the following weekend when a set of pot bearings located under the deck will be replaced by new 60kg stainless steel pot bearings.

    “A pot bearing plays a crucial role, supporting the weight of the bridge deck and allowing movement in response to changing temperatures and different loads.

    “The original pot bearings, which were identified during an inspection nine years ago, will be examined.

    “Depending on the results, hundreds of pot bearings may need to be replaced on up to 28 spans in stages over about two years.

    “There will be some diversions in place for southbound traffic over the next two weekends.”

    This weekend the lift will take place from 10.30pm, Friday July 13 until 4pm, Saturday July 14.

    Similar to other maintenance works on the expressway over the last few years, a section will be closed with traffic diverted off at Elizabeth Street, along Williams St and returning to the motorway at Alice Street.

    “To minimise disruption to traffic, we’re starting late on the Friday night after the completion of the Broncos-Warriors game at Suncorp Stadium,” Mr Emerson said.

    “The section of the expressway will re-opened to traffic by 4pm on the Saturday ahead of the Lions-Saints game at the Gabba and the Red-Waratahs match at Suncorp.”
