Access in and out of the seaside suburb of Sumner will be blocked for up to 30 minutes each evening over the next week.
Crown-owned, red-zoned properties above Main Rd are being demolished and as a safety precaution the road in and out of Sumner will be closed, between 128 Main Rd and Clifton Tce, intermittently each night from 9pm to 4am from tomorrow to Friday morning.
The road could be closed for 30 minutes at a time before opening for five minutes to allow traffic through.
The road closure was to protect the “minor possibility” demolition materials could end up on the road.
The demolition would occur above the area where there is currently a protective container wall.
The properties have been hanging from the cliffs since the quakes. Large portions of some of the once-multimillion dollar homes can be seen from the road. Containers have protected motorists from falling debris, including parts of the houses and rocks since the quakes.
Meanwhile in the central city, the final stage of Tuam Street’s transformation into an east-bound route begins today, on the stretch of road between Antigua St and Riccarton Avenue near the Christchurch Public Hospital, which will remain open while work is underway.
There will be no left turn from Antigua St into Tuam St from Friday. Traffic headed for the hospital and Riccarton Ave will be directed along St Asaph St and Hagley Ave.
The work will complete Tuam Street’s conversion into a one-way thoroughfare and give buses a direct route into the new Bus Interchange, due to open in winter.
