Deborah Rail Overbridge, south of Oamaru, detour this weekend


KiwiRail is carrying out bridge repairs at the Deborah Rail Overbridge south of Oamaru over three weekends, starting this weekend.

Deborah Rail Overbridge

This means that State Highway 1, under the bridge, will be temporarily closed with a detour in place during the day and Stop/Go controlling traffic overnight and outside the working hours. Fulton Hogan is contracted to do this work for KiwiRail.

The detour route – see map below

Drivers should expect short delays for the Stop/Go times and factor in extra time for the daytime detours along via Awamoa, Stonewall and Thousand Acre Roads.

  • The detour route has been approved for all overweight and HPMV vehicles. 

Dates for the temporary closures

  • 16, 17 & 18 April – Saturday to Monday. 
  • 30 April, 1 & 2 May - Saturday to Monday. 
  • 6, 7 & 8 May, Friday to Sunday.

 Work will start at 7.00 am on each of these days and finish at 8.30 pm. During these hours, the detour will be in place. Outside these hours, drivers will be able to stay on SH1 but should expect short delays with the Stop/Go single lane access and manual traffic management.

 NZ Transport Agency Journey Manager Graeme Hall thanked all road users for taking care around crews and traffic management staff and also on the detour route.
