    Traffic restrictions on Main South Road and Marion Road

    The works will be undertaken during inter-peak times, with speed restrictions of 40km/hr and 25km in place.

    The restrictions will be as follows (weather permitting):

    • Southbound traffic on Main South Road, Bedford Park (south of Flinders Drive) will be reduced to two lanes until Tuesday 16 September, 2014. These restrictions will be in place from 9.30am - 3:30pm weekdays and 7am-7pm over the weekend. One northbound lane will also be closed from 9:30am until 3:30pm.

    • Southbound traffic on Marion Road, Sturt, will be reduced to one lane from mid/late this week between the hours of 7am and 3:30pm for approximately four days.

    The restrictions will be in place to allow for the replacement of overhead signage at this location.

    These signage works are part of a rolling program of works. Details of further restrictions will be provided in the near future.
