asked the Secretary of State for Transport if he will list the stretches of the M4 motorway at present without a crash barrier and the dates such crash barriers are scheduled for installation.
The whole of M4 in England has central reserve safety fencing installed in accordance with normal standards.
asked the Secretary of State for Transport if he has any plans to increase the traffic carrying capacity of the M4 motorway between London and Reading.
The M4 motorway is at present being widened between the Heathrow Spur (juntion 4) and the new M25 interchange. I have no plans for further improvement at this stage but the capacity of the remainder of the motorway between London and Reading will be kept under review.
