Part of Park Hill Road Garstang (the B6430) will be closed to traffic and pedestrians from Monday July 27 to Friday August 7 for a new water supply connection to be installed.
The road’s one way order will be temporarily lifted and three way traffic control lights will be installed to direct traffic.
A 20 metre stretch of the road - 10 metres on either side of 7, Pringle Court will be completely closed to traffic but the temporary two way traffic system on other sections of the road will allow vehicles to access and exit local properties.
Several local bus services will be affected.
The County Council says the new alternative route is Park Hill Road-Windsor Road-Moss Lane and vice versa.
