Work has started on a 600 metre stretch of link road, which forms part of a project to reopen the Hemerdon tungsten and tin mine, near Plymouth in Devon.
The construction of the link road between Lee Moor Road and West Park Hill in Plympton is a condition of the 1986 planning approval for mining at Hemerdon, which is the fourth largest tungsten resource in the world.
Once completed in six months' time, the road will be used by both mining traffic and the public and be managed by Devon Highways.
Humphrey Hale, the managing director of Wolf Minerals which is managing the project, said: "We are very pleased to see work starting on the first major piece of infrastructure required for the Hemerdon project.
"It is an important step forward in our ambition to develop a world class and sustainable mining project."
Bardon Contracting is handling the link road construction.
