SMITHDOWN Road is in line for £1m of improvements.
It will be resurfaced from Lodge Lane to Gainsbourgh Road, after both the council and Scottish Power agreed to cover the cost.
The energy supplier agreed to put in £180,000 to the improvements after it damaged the already worn surface during a cable-laying project. Some disruption is likely as the south Liverpool scheme progresses over 10 weeks.
Council cabinet member for transport, Cllr Tim Moore said: “This is a really important scheme, which will bring Smithdown Road up to an excellent standard, bringing major benefits to motorists, cyclists, residents and businesses.
“We do, of course, apologise in advance for any inconvenience caused while this work is carried out. We will be doing everything we can to keep disruption to a minimum, but we believe that local people will recognise that the short- term delays will be worth it when they see the delivery of a brand new carriageway, which will last for many years.”
The work will take place in phases. The first stretch, from Woodcroft Road to Salisbury Road, will be resurfaced from January 14 to January 17.
The Gainsborough Road to Woodcroft Road section will happen over four successive weekends, beginning on January 19.
Salisbury Road to Underley Street will be done from February 5 to 18.
The council warned that, in order to make the improvements, the road would have to be reduced to one lane, and asked that vehicles use alternative routes where possible.
