Hartford Bridge Flats Junction Improvements

The addition of a fourth arm for right-turn provision allowing southbound traffic into the southern A327

Last update: June 2024

Latest Update

The construction work on Blackbushes Road is nearing completion and the road is due to reopen to traffic during the day on Friday 3 May 2024. (There is a significant number of new trees to be planted in the area; this work will be completed from Autumn 2024 to ensure the best survival rate of the new plants.)

Hampshire County Council has appointed Mildren Construction Limited as the main works contractor for the project. The main works started on Monday 23 October 2023, Blackbushes Road south of its junction with the A30 will be closed to all traffic. The road closure will remain in place until completion of the new road, planned for spring 2024. The diversion route is via B3013 Minley Road and the A30.  Initial site vegetation clearance started in late September 2023.

Scheme overview

This scheme will realign Blackbushes Road over a distance of approximately 250m south of the A30, moving it further west to create a fourth arm of the existing A30/A327 Hartford Bridge Flats roundabout. The addition of a fourth arm on the roundabout will complete an all-moves junction and provide direct access for traffic seeking to travel southbound on Blackbushes Road from the A327 southbound or A30 eastbound, and also for traffic seeking to turn eastwards onto the A30 from Blackbushes Road. This traffic will no longer be required to use a more convoluted route by u-turning at nearby roundabouts on the A30. This will result in journey time savings and also reduce the congestion and delay on the A30 Blackbushes roundabout junction which is currently caused by the high frequency of u-turn movements.

A joint funded Hampshire County Council and Department for Transport improvement scheme to replace the previous staggered junction arrangement with a three-arm roundabout solution was completed in May 2015. However, the scheme provided only a partial solution, as funding constraints precluded the provision of a fourth arm within Phase 1. This second phase will complete the scheme to ensure that the full benefits of the junction improvement can be realised.

The scheme will provide a new section of Blackbushes Road, approximately 250m in length, to connect directly with the existing A30/A327 roundabout junction. Alongside the construction of the new road itself, the scheme will include additional road resurfacing, drainage works, utility diversions and streetlighting improvements. The old section of Blackbushes Road will be closed to traffic, broken up, and the area covered with site-won material and low-level planting, to minimise the impact of the scheme on local biodiversity. Tree clearance will be required along the highway verge where the new section of Blackbushes Road will meet the existing road. The loss of these trees will be offset through re-planting within the area of land between the existing road and the new road, with a mix of species that will initiate the transition of the area to a natural woodland.

The scheme has been subject to two approvals by the Hampshire County Council Executive Lead Member for Economy, Transport and Environment:

Funding Arrangements
Funding for the transport capital delivery schemes is separate from the County Council’s revenue budget and savings proposals. In the majority of cases funding comes from external grants and / or Section 106 contribution from developers. This funding usually has conditions that strictly control on how, where and when it can be spent.
