Southern Expressway Community Safety Initiatives

16 Jan 2019

The department has committed to improve safety along its transport networks and to provide some practical responses to recent incidents of object throwing.

Safety improvements that include infrastructure upgrades and security initiatives are currently underway along the Southern Expressway.

These  include:

  • Installation of permanent anti-throw Screens along road bridges
  • Installation of temporary anti-throw Screens along road bridges
  • New and upgraded Close Circuit Television (CCTV) cameras at bridge sites
  • Installation of rock capping at bridge sites
  • Upgrades to fencing around embankments at bridge sites

Works completed to date include:

  • CCTV upgrades on nine bridge sites (with remaining sites completed by end October 2018).
  • Rock capping (mesh covering) near Honeypot Road and Beach Road bridges (with all mesh installations at bridge sites planned to be completed before the end of December 2018).
  • Installation of numbered signs on each bridge along the Southern Expressway to enable easier reporting of alleged instances of object throwing to SAPOL.
  • Temporary anti-throw Screens installed at all bridge sites.

What's Happening Next?

Installation of permanent anti-throw screens as part of DPTI’s commitment to improve safety along the transport network and to provide a practical response to the incidents of object throwing.

Weekend works are scheduled to commence from Friday, 7 December 2018 and are expected to be completed by late February 2019, weather permitting.

No weekend works will occur over the Christmas period from 22 December until 4 January 2019 and over the Santos Tour Down Under race weekend commencing 18 January 2019.
