A diversion route is in place following the closure of the M3 for emergency bridge repairs.

Just after 10.30am Monday, January 19, National Highways announced that emergency works were required between Junction 13 and Junction 14 due to an infrastructure defect.

Three lanes were closed southbound as a result of the works.

But, just before 3pm, National Highways confirmed they were closing the whole carriageway.

A diversion route is in place:

Approaching traffic is being diverted via the solid triangle symbol on road signs:

  • Exit the M3 at J12 and at the roundabout, take the second exit on to Allbrook Way.
  • At the following roundabout, take the second exit on to Twyford Road
  • At the next roundabout, take the third exit on to Romsey Road/Leigh Road.
  • Continue to re-join the M3 at J13

A National Highways spokesperson said: "Specialist service providers are currently in attendance working to carry out the required repairs.

"If this closure impacts on your planned route, please allow extra journey time. Plan ahead, you may wish to re-route or even delay your journey."
