Blackwatch Pass was reopened to both motorists and pedestrians yesterday morning after weeks of work on dangerous slopes.

The Ministry of Public Works commissioned the work, which included rock scaling as well as additional rock-face stabilisation.

The ministry noted that while the road is now open, there will still be ongoing fencing work and “shotcreting”, a process by which concrete is hosed on to a surface.

The road linking North Shore Road to Hamilton opened in 1934 and has been subject to falling rocks.

Plants growing in the stone work and gradual weathering of the exposed stone can bring down rubble.

The road was closed during daytime hours for remedial work by a Canadian team Cimota Inc.

They rappelled the slopes of the pass on high-strength ropes with pry-bars and pick to remove trees and rocks.

Work began on April 3 and was reopened yesterday morning.
