A public consultation has been launched on plans to introduce a rapid bus service along the A4 in Slough.
Residents and businesses are being asked to give their views on the proposed scheme, which would involve localised widening of the A4 and upgrades to several junctions.
In addition, service roads that run parallel to the A4 through Slough Trading Estate would be turned into bus lanes.
The council's cabinet approved the £8 million scheme - known as SMaRT (Slough Mass Rapid Transit) - at a meeting on September 15th.
Savio DeCruz, head of transport for Slough Borough Council, said: "The A4 is a crucial link between Maidenhead, Slough and Heathrow, and improving bus times will play a major part in reducing congestion and increasing economic efficiency."
People are being asked for their overall views, as well as specific questions about parking, one-way systems, bus stops and widening in certain roads.
