Other roads near Braham Street, including Mansell Street, Leman Street and Alie Street, will remain one-way but will get new pedestrian crossings and "advanced stop" bays for cyclists. Pedestrian underpasses will be replaced with street-level crossings. Preliminary work by engineers has started and major work will begin within weeks, with the traffic "switch" - when cars can begin to travel in both directions along Whitechapel High Street - planned for August.
