Highways England is installing new steel safety barriers along the route between the 2 roundabouts which link the A56 to the A680.
Work was due to start in November, but was delayed as construction teams worked on other schemes. Work will now start on Saturday 9th January.
A pedestrian crossing which links Rising Bridge Road to the Hall Park housing estate is also being upgraded, and a new island will be created in the centre of the A56 to make it easier for residents to safely cross from one side to the other.
John Lyssejko, Project Manager at Highways England, said:
The new steel barriers and better pedestrian crossing we’re installing on this section of the A56 should help to improve safety for everyone who uses the route.
The pedestrian crossing links two residential areas of Haslingden and we’ll be making changes to the layout, as well as creating a new island in the centre of the road, that will make it easier and safer to cross.
We’ll need to have some lane and overnight closures in place while this work is carried out, but it will bring long-term benefits to the A56 when it is completed.
Some lane closures will be in place between 8pm and 5am, Monday to Friday, and 24 hours a day at weekends.
The A56 will also be closed overnight on Friday and Sunday nights on some occasions while contractors set up and remove the traffic management cones and barriers. Clearly signed diversions will be in place.
The scheme is now due to be completed in March and is part of a phased package of improvements Highways England is delivering along the A56.
