Motorists have been warned of more than a week of closures on a M27 sliproad and the A32 due to a nearby development.
Hampshire County Council says they will take place overnight between Monday, October 14 and Friday, October 25.
The work, which will impact the M27 and A32, will support the Welborne Garden Village development.
The roads will then re-open from October 25 at 6am with one lane of traffic in each direction under a 40mph speed limit.

Between October 14 and October 22, 2024 there will be a closure on the A32 in both directions impacting lane 2 with no access onto the M27 eastbound sliproad.
The work will take place between 9pm and 6am for nine nights with access to the motorway still possible for northbound traffic.
The closures allow surveys to be completed in the central reservation and utility works to be undertaken by Portsmouth Water.
A signed diversion route will direct drivers via Wickham along the A334 and A3051 to the M27 Junction 9 and the A27.
Between the hours of 9pm and 6am on October 23 and October 24, there will be a full closure of the A32 as well as the M27 westbound sliproad.

This is to allow for a new traffic management layout to be installed.
During these closures, the A32 traffic will be diverted via the A334 and A3051 to M27 Junction 9 and the A27, while road users wishing to join the A32 northbound will be diverted to M27 Junction 9 and will follow the A3051 and A334.
Escorted access will be provided for directly impacted residents, businesses, and emergency vehicles.
A county council spokesperson said: "The closures will enable utility works to be undertaken by Portsmouth Water, including surveys to locate the depth and position of existing services.
"In addition, a new traffic management layout will be installed by Hampshire County Council’s contractor VolkerFitzpatrick, to support the flow of one lane of traffic in each direction from Friday 25 October."
