The Highways England scheme, which is taking place between Low Newton junction and Meathop roundabout, is due to start on Monday (9 November) and be completed by Sunday 20 December.
Highways England Project Manager Peter Gee said:
This is vital work to ensure drivers and other road users can continue to enjoy safe journeys along this section of the A590 with the verge-side safety barriers on both the westbound and eastbound carriageways being replaced by new barriers.
We will need to close the carriageways overnight for 3 nights as we install and remove the traffic management cones and barriers for the work but otherwise the road will remain open at all times. We’ll have clearly signed diversions in place when carriageways are closed overnight, suitable for all types of vehicles.
The work will be delivered in 2 phases, with barriers first being installed alongside the eastbound carriageway followed by work along the westbound carriageway.
Installation of traffic management in the eastbound carriageway will take place using a full overnight closure of the carriageway between 8pm on Saturday (7 November) and 6am on Sunday (8 November).
On Saturday 5 December, both the eastbound and westbound carriageways will be closed overnight as the traffic management is moved over to the westbound carriageway. A final overnight closure – to remove traffic management from the westbound carriageway and complete the scheme – will take place overnight on Saturday 19 December.
When carriageways are closed, a signed diversion will be in place between Newby Bridge and Meathop roundabouts using the A592 and A591 via Windermere.
When work is taking place on a carriageway, one of the 2 lanes will be closed with a 50mph speed limit past the roadworks in the open lane.
Local road users are also being advised that central reservation gaps will be closed for the duration of the work, with westbound access into and out of the B5271 Cartmel Road closed.
