Regency Road overpass bridge spans installed
The South Road and Regency Road intersection reopened to traffic ahead of schedule at approximately 9pm last night, following the completion of works to transport the centre spans for the Regency Road overpass bridge.
The two overpass centre spans each weighing around 1300 tonnes, were assembled ‘off-site’ at the Polonia Reserve compound.
During 4 – 11 January 2021, the centre spans were individually transported from the Polonia Reserve compound to their final location, over Regency Road, using Self Propelled Modular Transporters (SPMTs).
After the centre spans were installed, the back spans and precast concrete deck slabs were craned into place.
The centre spans and back spans were produced by local South Australian Company, Bowhill Engineering, with the majority of the steel also sourced from South Australia.
The R2P Alliance is proud to have reached this significant milestone and the project team would like to thank the local community and motorists for their patience during these major works.
Works will continue at the intersection, with the following works to be undertaken to prepare the overpass for traffic:
- concrete deck and expansion joints,
- concrete road barriers in the middle of the overpass to separate northbound and southbound traffic,
- steel barrier railing.
- connection of power, Intelligent Traffic Systems: and
- cover plates to overpass abutment and piers
- placement of water-proofing on the overpass deck and then laying of asphalt,
- grouting of bearings at the overpass abutments, and
- finishing works to plaza areas underneath the overpass at the South Road and Regency Road intersection.
The Regency Road overpass is expected to open to traffic in mid-2021.
