MOTORISTS are being warned to expect traffic chaos on one of the busiest roads in St Helens.
Drivers are being given advanced warning of severe queues anticipated around the busy Windle Island junction from Monday, August 8.
The work is set to be carried out to replace the ageing traffic signals at the East Lancs-Rainford bypass junction.
Dual headed LED signal heads will be installed on seven metre high posts on the three main high speed approaches.
Council chiefs say the changes will make the signals more obvious from a greater distance away and will provide energy savings.
Improvements to road markings will also be made, along with the installation of some guard-railing.
Due to the existing cabling layout at the complex junction - inherited by St Helens Council from the Highways Agency - Town Hall chiefs say it will be difficult to isolate individual traffic signal posts.
It is proposed to switch off the existing traffic signals and funnel the traffic through the junction in single file on each approach, using temporary traffic signals.
This will enable the highway works to be carried out safely but will inevitably cause severe queuing on each approach of the junction.
To ease congestion, it is proposed to carry out these works around the clock until works are complete - a preiod expected to be five days.
Advanced warning of the queues will be provided a fortnight before the start of the roadworks in Variable Message Signs on the main approaches.
