Colas has formed a joint venture with VolkerFitzpatrick to deliver the Tipner Interchange junction on the M275, a park-and-ride and southbound bus priority lane for Portsmouth City Council.
This project is helping to maximise benefits gained by the city from Colas' PFI contract.
The work is key for the regeneration of the Tipner area as well as benefiting Portsmouth as a whole by helping reduce congestion on the roads and encouraging businesses and visitors to the city.
The works involve:
- the construction of a new roundabout located at Tipner Lane with associated verging and di-verge slip roads
- a new bus lane
- removal of the existing single span gantry and the installation of a new replacement full-span gantry
- installation of new advanced warning signs to replace the existing ones to the southern gantry near to Rudmore Interchange
- construction of park-and-ride car park for more than 600 vehicles
- construction of park-and-ride building with waiting facilities for customers
Transport minister Baroness Kramer formally marks the completion of the Tipner Inerchange junction on the M275, the park and ride and southbound bus priority lane with a visit.

Construction of the on/off slip roads on the southbound carriageway commences. This will be coupled with the new bus lane including associated drainage, gabion wall & petrol interceptor installation.
Auger boring for the gantry on northbound carriageway was carried out - these holes were drilled into the motorway in preparation for erecting and connecting the new gantry.
Drainage pipes were laid on northbound slip road.
We completed sheet piling on 16 meters of southbound carriageway - this involved inserting metal poles into the embankment to stabilise it.
We continued with the earthworks along the northbound carriageway. We also started to raise the level of the ground using crushed concrete so that it forms the foundation for the new slip road.
A 40mph speed restriction and hard shoulder closure was implemented so that we could construct the on and off slip roads.
Enabling works for the installation of closed-circuit television (CCTV) and speed enforcement system, were completed and the existing communication system was closed for the duration of the works.
Work on Tipner's new motorway junction and park and ride officially started after the site was opened on 9 January by Local Transport Minister Norman Baker. Along with representatives of Portsmouth City Council, the minister dug the ceremonial first sod of earth on the site to mark the start of the project.
