TfL has released two consultations to improve London Bus services for Stratford and routes 53 and 363.
From TfL consultations
The London Borough of Newham has developed proposals that will transform Stratford town centre. This will include removing the gyratory around the Stratford Centre and introducing two-way traffic movement on Great Eastern Road, The Grove, Romford Road and Broadway.
The current configuration of the gyratory prevents the operation of a simple bus network (i.e. one that serves stops on both sides of the same road). Two way operation would simplify the bus network and allow buses to serve stops on both sides of the road. In particular, it would allow Stratford bus station to be served in both directions by westbound routes serving Broadway and Stratford High Street.
