£1.8 million scheme to upgrade A10 roundabout at Ely is due to get underway on Tuesday.
As part of the Lancaster Way Business Park expansion planning approval, improvements to the BP roundabout are required that will not only improve capacity to tackle the additional traffic, but will benefit people by providing more than 2,500 new jobs.
This work follows a feasibility study which showed the main cause of the existing local congestion was caused by the BP roundabout and identified improvements that would be required to provide capacity for the additional traffic generated by the expansion of the business park.
Work will start at the BP roundabout which consists of widening all approaches to the roundabout providing at least two lane entries.
The eastbound arm of the roundabout will have three lanes giving a dedicated left turn lane onto the A10 north.
The exit of the A10 services will be restricted to left turn only and any vehicles wishing to head west will have to go round the roundabout.
The eastern leg of Witchford Road is going to be closed for the duration of the works to reduce the time taken to complete the scheme and will also act as the site compound. As a large proportion of the works are in front of the A10 services, pedestrians will be diverted via a temporary footpath on the south side of the A142 with temporary lights crossing over the A10 and A142.
The roundabout will be under three-way temporary traffic signals 24/7 for the duration of the scheme meaning delays are possible. At the end of the programme there will be five nights (8pm-6am) of full road closures for the resurfacing and road markings.
The work is due to be finished by December.
