Bassett Avenue A33 - Major road improvements

Latest news

Bassett Avenue overnight resurfacing was completed on time and the final addition of anti-skid surface treatment at the approach to the three pedestrian crossings is planned to be carried out from Monday 30 April for up to five nights. Working from 8pm until 6am.
To carry ou the work Bassett Avenue will need to be closed be closed from Winchester Road Roundabout up to Chillworth Roundabout during the overnight work. Access will only be maintained for properties with not alternative access. All those properties who are permitted access have been writen to and should have received access permits. See map below for affected roads.
Thank you for your patience over the last two months and for all the positive feedback, we really appreciate it. Hopefully the new improved road will last at least another 16 years if not a while longer. 

Travel advice

The second phase of works overnight on Bassett Aveune are expected to cause some disruption. If you use Bassett Avenue in the evenings after 8pm during weekdays, please plan your journeys wherever possible and allow extra time. Alternative routes will be signed. 

Alternative routes for traffic to and from the M3

We are advising drivers using the M3 motorway to use alternative routes into and out of the city via the M27 junctions 3 and 5. Traffic reaching Winchester Roundabout or Chilworth Roundabout will be diverted via Bassett Green Road and should expect delays. See this map for more details

Bassett Avenue - Frequently Asked Questions (FAQs):

Why are we doing the work on Bassett Avenue now?

The timing is partly down to the deterioration of the road and availability of funding this year. The specific timing is to avoid conflict with other major highways work also planned to be undertaken in the region in 2018/19. 

Why wasn't this anti-skid treatment carried out at the same time as the resurfacing? 

Unfortunately the new surface doesn't fully cure and dry out for several weeks and applying the anti-skid treatment too soon would lead to the surface pealing off in a very short time.  

What alternative travel options are available?

We are advising drivers using the M3 to use alternative routes via the M27 junctions 3 or junction 5. Local traffic is being diverted via Bassett Green Road. As the closure is overnight we do not anticipate significant delays but the diversion is a slightly longer route so please plan your journey. To see a larger divertion map click here.

For information about other ways to get around during the road works it is worth checking out this useful online journey planner that combines bus, train and ferry travel to get you where you need to go; it can also show you the best cycle routes to your destination.

Why is Bassett Avenue being closed?

The new material has to be laid in large continuous sections and given time to cure before traffic can travel over it. To work around the surfacing requires at least three lanes to be closed. By closing the road fully we can complete two sides of the road surfacing in one night halfing the duration of the work and significantly reducing the cost. We hope that by doing the work in as short a time as possible and overnight when the road is least busy we will reduce the disruption for most people. 

Who is funding this work?

This work is being undertaken as part of the city’s annual highways maintenance budget funded by Southampton City Council.
