The specialist piling and coring equipment at Bouldnor, which drives the steel sheet piles as far as 16 metres into the ground.
ISLAND Roads says it is pulling out all the stops and working with utility companies to ensure the major road stabilisation scheme at Bouldnor is complete before the April 4 deadline.
It says it is working seven days a week and extended hours through the night. It has installed more than 600 of the 750 piles to strengthen the historically unstable highway.
Some Bouldnor residents have complained about noise, disruption and long diversions and the fact the road was closed at all.
A taxi service organised by Island Roads was laid on but some residents complained they did not receive letters telling them about arrangements.
Island Roads’ geotechnical director David Gibby said: "We realise that, while necessary, the closing of Bouldnor Road does cause inconvenience for residents, so we are taking all the steps we can to make sure work is completed as quickly as possible.
"I am pleased to say the work is progressing well and we thank residents once again for their continued patience and support in enabling these works to be completed safely and successfully.
"Work has included installing 400 metres of footway, widening it where necessary between The Viewpoint and The Mount, and installing 200 metres of new drainage along this section of road."
He said as part of the scheme, The Viewpoint car park, would be landscaped with additional planting to encourage wildlife, while the village green was also being re-profiled to make it easier to maintain.
Island Roads was improving the Revetment and supplied labour and materials to help Yarmouth Primary School create raised flower beds, as part of the company’s community involvement scheme, he said.
