Christchurch City Council awarded the NZ$12m (£6m) contract to McConnell Dowell.
The road between Lyttelton and Evans Pass, near Sumner, was closed because of rockfall hazards. Prior to the earthquakes, the road served as an alternative route to the port and in and out of Sumner and Lyttelton, and was a popular link for cyclists.
The McConnell Dowell team will oversee and carry out scaling and ground support of the bluffs above Sumner Road, excavate a large catch bench below the bluffs to catch any falling rocks, and construct a large reinforced earth embankment. The measures are designed to protect future road users from the risk of rockfall.
