"The road from Silloth to Maryport is a vital link for communities along the Solway coast and as the local member who has been underlining the importance of keeping the road open, I'm pleased that engineers are now pulling out all the stops and getting the vital work started before Christmas.
"Without this work starting immediately, there was a very real risk that part of the road would simply have disappeared into the sea and I was all too aware of the consequences that would had for the local road network."
Work has begun to stop part of a Cumbrian road disappearing into the sea.
The 280 metre stretch of the Maryport to Silloth Road will be wrapped in a rock armour to prevent further erosion.
Due to the natural coastal erosion caused by it's proximity to the Solway Firth, around 20 metres of the road has worn away in the past two years.
Cumbria County Council habe approved the £320,000 funding for the project, which will see a new defence built from around 7,000 tonnes of stone and other material.
The road is expected to remain open to traffic while the work is underway under a single-lane traffic system.
