A four-month project to install a new pedestrian crossing on the A27 at Park Gate is due to start next week.
Hampshire County Council has already posted signs warning that roadworks are due to begin from April 15 as part of the £360,000 project to install a Toucan crossing between the Hunts Pond Road roundabout and the Telford Way junction as well as new cycle paths between there and Swanwick railway station.
There will be lane closures on the A27 and Botley Road at different times during the length of the project which is likely to lead to significant congestion at peak times.
The scheme, which is unlikely to be completed before August, runs alongside six months of roadworks on the M27 at junction nine that began last month. That work is the responsibility of the Highways Agency.
The crossing for pedestrians and cyclists, along with ancillary works to create more cycle routes and walkways along Botley Road, has been designed to improve access for people travelling between residential areas on the north side of the A27 and Park Gate Primary School on the south side.
When works take place in Botley Road, eastbound or westbound traffic will be diverted via Bridge Road and Station Road – or vice versa depending on which side of Botley Road is closed.
Residents opposed to the proposals raised concerns that it would risk more accidents for those getting across the A27 at the new crossing and then having to negotiate the very busy Hunts Pond Road where there is no crossing.
