The multi-million pound transport scheme to get thousands of workers and residents in and out of a new town set to be built on the former MG Rover plant at Longbridge has been set out.
The scale of plans for 2,000 homes and the creation of 10,000 jobs means junctions on the M42 and M5 will be altered and motorway-type slip roads installed on the A38 Bristol Road.
Developer St Modwen and the city council said they were confident they would be able to keep vehicle movements to fewer than 5,000 each morning and evening through a combination of park and ride schemes, cycle ways and walking routes.
But hopes that a rail link between Frankley and Longbridge could be created appear to have been dashed because of fears over cost.
Instead a high-speed bus lane will be used to shuttle commuters between the two towns.
The masterplan came under the spotlight during the two-week inquiry into the blueprints for the £750 million transformation of the site.
Chris Haynes, from Birmingham City Council, said the priority would be to keep traffic away from rural roads.
“The challenge is to try and restrict the flow of traffic to main roads like the A38 Bristol Road and keep it away from residential areas.”
Jason Tait, of St Modwen, said full consideration had been given to including a rail link between Frankley and the redevelopment site but was deemed prohibitively expensive and would lead to a “segregated community”.
Responding to claims by a resident at the hearing that the decision had been driven by a desire to maximum space for housing, he said: “There’s a complete naivety about regeneration which misunderstands the sensitivity and viability of this project.”
The hearing is expected to last two weeks and a planning inspector will decide whether to approve an amended action plan for the site.
