Major work underway to make the gyratory comprised of Broadway, The Grove, Great Eastern Road, and High Street into a two-way street.   Changes being made to traffic lights and junctions with High Street, Angel Lane, Romford Road, and The Grove.   Additional lanes seem to be on the way on G.E.R. (loss of some footpath?).  Changes to bus routes too.   Completion planned for 2019?  But work being carried out in 6 phases.  General idea here: https://www.newham.gov.uk/Pages/Services/Stratford-town-centre-improvements.aspx
