Floods Minister and local MP Rory Stewart says the re-opening of the A591 shows that Cumbria is very much "open for business".
The major Lake District route had been closed since the Storm Desmond floods on 5 December.
But the MP for Penrith and the Border says there's plenty more work to do, with a £10 million flood defence repair programme underway.
The work to open the A591 early shows how we are standing firmly behind communities hit by December's flooding with investment in infrastructure, new flood defences and promoting the region across the world. I am delighted Highways England has managed to do this at such high quality in very difficult circumstances.
We are showing the country, and the world, that Cumbria and the Lake District are back open for business.
Get all the facts and figures behind Highways England's work to repair the A591 between Keswick and Grasmere.
The flood-hit A591 has now re-opened, connecting the north and south of the Lake District.
