A602 improvements, Stevenage to / from Ware

We've nearly completed our improvements to sections of the A602, from the south side of Stevenage to the A10 in Ware.

The scheme is due to be completed in June 2018.

We're working to ensure that minimal disruption is caused, especially at peak times. We're doing this by carrying out more work at night.

Whilst works are underway, we've had the chance to do some necessary tree and drainage maintenance on Westmill road, and arranged for a local water company to make improvements on their water mains.

This will reduce the need for more roadworks in the future.


Why we want to change the A602

The A602 is a very busy road, but there are problems in places:

  • vehicles turning right are blocking traffic behind, causing delays
  • tight bends and poor visibility make the road less safe than it could be
  • often long queues at junctions.

Improvements we're planning to make

We want to improve the major junctions, reduce delays and make the route safer. We want to make improvements to these locations:

  • Hertford Road junction
  • A119 roundabout
  • Ware Road
  • Sacombe Pound junction
  • Stony Hills junction
  • Anchor Lane roundabout
  • Westmill Road
  • A10 junction.

Steps to complete the project

Step 1: Early options

We looked at a number of options for improving the A602, to reduce traffic congestion. We put this together into a business case.

Step 2: Seeking funding

The total cost for this scheme is £19.4 million.

Funding has been approved by the Local Enterprise Partnership and Local Transport Body.

Step 3: Developing the scheme

The Local Transport Body consulted on the business case. The consultation ended in August 2014 and helped us decide that the project is value for money.

We held a public exhibition in May 2015. This gave us a chance to find out what you think about the project prior to submitting the planning applications.

A report was put before the Development Control Committee following a period of consultation.

Step 4: Getting permission / planning applications

A total of 4 planning applications were submitted.

We submitted 2 in May 2016:

  • Hertford Road junction
  • Anchor Lane junction, Westmill Road, A10 junction.

The works are currently underway and are expected to be completed in Spring 2018.

We then submitted the final 2 planning applications in July 2017 for:

  • A119 junction
  • Ware Road Improvements, from Heath Mount School to the Stony Hills junction.

These were considered at the Development Control Committee on 25 January, and the works are expected to begin in summer 2019.

Step 5: Construction

Construction works started on 29 August 2017. Improvement works to the A602 between Ware and Stevenage will be completed at the end of May, later than previously scheduled.

The new junction at the A602 Hertford Road, Stevenage will not be fully operational until the traffic signals are commissioned in the first week of June. Other work such as landscaping and the removal of site compounds will continue throughout of June.

Hertford Road junction, Stevenage

Changes have been made to the bus only access at the Hertford Road / Ashdown Road junction to allow for 2-way traffic. This will be returned to bus-only once the new Hertford Road/ A602 junction is opened.

Hertford Road at the A602 will be closed to all traffic until the new traffic light junction is completed. A diversion route via Broadwater Crescent and Ashdown Road is in place.
