M4 roadworks in Berkshire to begin
Roadworks to improve traffic flow and congestion at a busy section of motorway in Berkshire are set to begin.
Nearly six months of works will start this weekend to widen slip roads leading to junction 10 of the M4.
The road layout will also be improved as part of the £5m project.
The scheme is part of the government's £317m programme to upgrade motorways and major trunk roads by the summer, the Highways Agency said.
Project sponsor Ed French advised people using the junction to "plan their journeys and allow extra time".
He said the majority of work would take place overnight.
Work will involve widening the north and southbound slip roads from the M4 onto the A329 to allow for two new lane merges.
The roadworks are scheduled to be completed by June.
