Work has started on three pieces of work at the junction of West Derby Road and Green Lane.
The work, which will take about 12 weeks has been coordinated to minimise future disruption to traffic.
It involves improving pedestrian facilities including providing new Puffin crossings, a wider island to accommodate more pedestrians safely and a new pedestrian guardrail.
The second piece of work will see new street lighting, an improved footway outside the shops and carriageway resurfacing.
And during this programme National Grid are also carrying out protection works to a 15 inch gas main.
A council spokesman said: “Inevitably there will be disruption to traffic but by doing this work in a coordinated manner we are trying to reduce the amount of inconvenience. The alternative would have meant this road being disrupted on three separate occasions. It would be helpful if, where possible, drivers used alternative routes.”
Normal working hours will be between 8.am and 16:30pm on seven days a week.
Due to the nature of the works, access on to the footway will be restricted and at times will need to be controlled on occasion for health and safety reasons, however we aim to restrict periods of inconvenience to a minimum.
Two lanes will kept running through the works, except when full resurfacing works take place which is likely to be towards the end of October.
