About project

Higgins
 
Supply of 7.7m diameter structural plate overpass - 52m long
Supply of 500m Ezy-Guard guardrail with ET2000 end-terminals
Supply of 2km Safence WRSB with TL3 non-release terminals

As part of the $6.4 million upgrade of the 2-kilometre stretch of state highway halfway between Blenheim and Seddon, the rail tunnel bypasses the ageing Dashwood overbridge and enables motorists to pass over the highway on a straighter, safer alignment. The tunnel was built to strict KiwiRail requirements, and the work was specially programmed to ensure it did not interfere with train schedules.

The 2km realignment, removes a number of dangerous curves and ensures straighter, high-visibility approaches to the new overpass.

The project is the largest highway construction project in Marlborough since the new Awatere Bridge was built in 2007.
