"When Colchester council approved the plan, in about 2007, it insisted that all private motor traffic enter and leave the estate via an access on to the A134 (Cordelia Drive), near to the A12 but at the farthest point from the town centre. ...
A year ago, the developers, Mersea Homes and Countryside, decided they didn't like this arrangement and applied to scrap the bus gate. They hedged their bets and also asked to move the bus gate into their estate, giving 160 homes access to Mile End Road.
Colchester council rejected the scrapping of the bus gate but granted a temporary access for five years to be covered by a legal agreement.
The developers decided to go to appeal." (blog)
