Improvements to the southbound carriageway and motorway bridge on the M6 near Garstang in Lancashire begin today, Monday.
The £100,000 project involves installing new bridge joints onto the bridge which crosses the motorway between junctions 33 and 32, followed by repairs to the southbound carriageway, and will be completed by October 10.
The motorway will remain open at all times, although there will be some overnight lane closures of two lanes with one lane remaining open between 8pm and 6pm.
Depending on the location of the work, traffic will run in a single lane on either lane 1 or lane 3 on the southbound carriageway at these times.
A temporary 50mph speed limit will be in place for the safety of road workers and drivers.
The work will take place in two phases, with the first phase for bridge joint installation taking place from September 23 to 25 and the second phase taking place from October 7 to 10.
Highways Agency project sponsor Peter Gee said: “This is an important, if routine, repair project which will ensure that users of the M6 in Lancashire can continue to enjoy safe, smooth and reliable journeys.
“The motorway will remain open at all times and drivers should only experience a short delay to journeys passing through the roadworks. We would like to thank drivers for their patience in advance.”
