In 2018 Guildford Borough Council identified three key junctions as traffic hotspots where peak time queues cause significant delays. A hotspot is a junction that has insufficient capacity for the volume of traffic using it and has an adverse impact on the efficiency of the highway network in a wider area. The Guildford Hotspots project aims to reduce traffic congestion at these hotspots. One of these junctions is the A331 and A31 junction in Tongham.
This junction is located at the southern end of the Blackwater Valley. It involves the construction of a slip lane for vehicles travelling southbound on the A331, wishing to travel eastbound on the A31, removing the need for them to use the roundabout. The roundabout will be part signalised and incorporate improved facilities for pedestrians and cyclists, thus supporting vulnerable road users.
Ground penetrating radar surveys are due to take place on the roundabout from 18 January 2021. The works will be carried out under overnight lane closures, from 8pm to 6am, for approximately one month.
We are also starting advance site clearance works from the 18 January during the day. These clearance works are taking place following carful ecological surveys and need to be completed before bird nesting season starts. The clearance works are needed to make space for the proposed new road layout and to provide visibility splays for the public using the highway. To enable the works to take place safely we do need to close the "Christmas Pie Cycle route", this will be closed until 29 January, signs for the closure and a diversion route will be erected. If the works are completed prior to the 29 January the path will be reopened and the diversion signs removed.
A start date for the main construction works will be confirmed at a later date.
