The Contract Works comprise of:

Replacement of the Mangaotama Stream Bridge existing superstructure with a new composite concrete deck and steel girder superstructure on the existing foundations. It is envisaged that the Contractor will utilise full road closure to undertake the superstructure replacement with an Early Completion Bonus incentivising reduced traffic disruption.
