A133 Ipswich Road/Harwich Road improvement scheme, Colchester

Latest News - 31 July 2020: A133 Ipswich Rd works Update: Temporary one-way system for A133 / Ipswich Rd South in place from 3 August until 7 September

The A133 Ipswich Road roundabout highway improvements are continuing, with works now well underway on the replacement of the existing retaining wall adjacent to the Clacton to Colchester railway mainline.

To complete this critical phase of works Essex Highways need to make Ipswich Road South one way for traffic leaving northbound from 3rd August until 7th September. The carriageway space this will provide will enable the installation of the southern end of the new strengthened cantilever wall, a major part of the new Ipswich Road roundabout improvements. 

We have carefully planned the operation to keep traffic flow possible northbound as this will alleviate congestion for traffic leaving the town whilst the East Gates railway crossing is down.

We would like to thank you for your patience and co-operation whilst we undertake these improvements. You can read the latest scheme update from the contractor here

A133 Ipswich Road/Harwich Road improvement scheme, Colchester

About the scheme

We are pleased to announce that Eurovia have been awarded the contract and begun construction of this improvement scheme in September 2018 and are planned to remain on site until Summer 2020. The work start date has changed however the expected duration is planned to remain the same. The whole project is expected to be finished, with improved traffic flow through the whole area towards the latter part of 2020. The Harwich Road roundabout up to Ipswich Road roundabout is still planned to be completed this summer.

The scheme will see the replacement of the double roundabouts located at Ipswich Road and Harwich Road with a single roundabout at each location. The carriageway between Ipswich Road and Harwich Road junctions will also be widened to accommodate two formal lanes in each direction. The scheme will include upgrading existing pedestrian crossings to signal controlled crossings and general improvements to the current off-carriageway cycle and footway provisions.

The scheme will improve the performance of these two key intersections on the A133 and renewal of the infrastructure will reduce maintenance costs. It will also improve the existing highway assets including the strengthening of two retaining walls, one between Ipswich Road roundabout and the adjoining railway line and another between Ipswich Road roundabout and the Waitrose Car Park. The Scheme has also supported the Cowdray Bridge refurbishment, now being progressed separately through the structures capital maintenance programme.

It is recognised that this is a traffic sensitive site and local residents and businesses will have a keen interest in the work phases and traffic management.   With this in mind, we held a ‘Meet the Contractor’ drop-in session with the Eurovia team to discuss the arrangements in place on Wednesday 5th September 2018.  We were pleased with the turnout and received positive feedback, especially around the road layout, crossing upgrades, the new zebra crossing and the new slip lanes. We hope that we were able to reassure residents and provide contacts for any future correspondence.

Various temporary Road closures will be required during the project, the sections of road affected will be Ipswich road (to the south and the north of the roundabout) and Harwich Road (to the south of the roundabout). Directly affected residents/businesses will be notified in advance through letter drops and signage on site. Also we will be making a continued effort to support all communications by putting updates out via our website and Social media. A single road only to be shut at any one time. 




How will it affect you?

Whilst efforts will be made to keep traffic congestion to a minimum throughout these improvements, it is recognised that works will be undertaken in traffic sensitive areas and there is likely to be disruption to normal traffic flows.  Motorists are advised to allow extra time travelling through the area.

Pedestrian diversions will be in place where necessary and advertised locally.
