Motorists using the M6 are being warned that a rolling programme of repairs to the central reservation barrier between Garstang and Lancaster is now under way.
The £53,000 Highways Agency project is focusing on three sites between junction 32 for Broughton and junction 34 for Lancaster.
The work will be done in three phases, with the first having taken place last week on a site north of junction 33 at Galgate.
The work will recommence on Friday, August 2 north of junction 33 at Galgate, and then finally there will be work at two sites near Garstang between junctions 32 and 33 between Sunday, August 4 and Friday, August 9.
Drivers are being advised that, during each phase of the work, the outside lane in each direction of the motorway will be closed during the day between 6am and 8pm.
Between 8pm and 6pm each night, one or two lanes of the motorway will be closed in each direction. In all cases, a 50mph speed limit will be in place on the approach to and past the roadworks for the safety of road workers, as well as motorway users.
Highways Agency project sponsor Peter Gee said: “This is a routine repairs and maintenance project to ensure drivers can continue to enjoy safe journeys along the M6 through this part of Lancashire.
“Neither the daytime single lane closures or the extra lane closures overnight should cause too much inconvenience to drivers but we appreciate that motorway users do like to know what work is going on.”
