The Department of Transport has praised those working on the A591 as it was announced the road would re-open ahead of schedule.
The road has been closed since December after extensive damage was caused by Storm Desmond.
The main route between the North and South Lakes is now set to open on May 13th, which is eight days sooner than expected.
It's estimated that the road closure was costing the local economy around £0.5m for every day it was shut.
The road will now be open in time for the Spring bank holiday, allowing traffic to travel between Grasmere and Keswick.
The announcement was made by Transport Secretary Patrick McLoughlin, who has been visiting parts of the county hit by Storm Desmond and Eva.
Mr McLoughlin was joined by Highways England Chief Executive Jim O’Sullivan and Keith Little, Cumbria County Council’s Cabinet Member for Highways, to see how work was progressing on the A591.
The Transport Secretary also visited Pooley Bridge and Eamont Bridge, both of which were severely damaged in the December storms.
