The £270,000 Highways Agency scheme will tackle the worn drainage system in the hard shoulder and central reservation of the southbound carriageway between junction 34 at Lancaster and junction 33 at Galgate.
Highways Agency project sponsor Peter Gee said:
This is vital work to upgrade the drainage system along a short stretch of the southbound carriageway and reduce the potential for surface flooding during heavy downpours as well as run-off into neighbouring fields.
We will be doing the work outside peak travel hours during the day to minimise disruption to motorway users.
The work, just north of junction 33, will start on Monday September 15 and should be completed by Monday 22 September. All the work will be taking place between 10am and 3.30pm each day with either lane 1 or lane 3 closed over a short stretch of the carriageway. A 50mph speed limit will be in place for safety reasons past the roadworks.
