» The Greenway north of Stratford High Street (to enable Crossrail work, and the relocation of Pudding Mill DLR station) (closed May 2009, until late 2014) (diversion required) (will reopen temporarily during the Games as part of the main southern entrance through the Greenway Gate)
» The ramp from the Lee Navigation towpath up to the Greenway (to enable Olympic security-related infrastructure works) (closed earlier this year, until 30th September 2012)
» The pedestrian footpath at the southern end of Wick Lane, round the back of Bow Quarter (to enable Crossrail sewer strengthening works, until July 2014)
Monday 30th April
» Access from Wick Lane to the western end of the Greenway will close from 30th April. This is to allow completion of security facilities at the Victoria Gate entrance to the Olympic Park. From the View Tube, it will only be possible to walk along the Greenway as far as the point where the warm-up track crosses. Entrance open to ticketholders during the Games. Reopens 30th September. Diversion required: along Dace Road to Old Ford Lock, then south along the Lee Navigation towpath to Stratford High Street, then trek down to the Greenway.
Saturday 19th May
» Access from Pudding Mill Lane to the Greenway will close at 8am on 19th May, ten weeks before the start of the Olympics. The Greenway closure is required for "operational and security reasons". Reopens 30th September. The following become impossible: i) Access to the Greenway between Wick Lane and Stratford High Street ii) Access to the View Tube, which closes on 17th May (final art exhibit closes 16th May) iii) Going up onto the Greenway to look at building work on the Olympic site
Tuesday 3rd July
» The Lee Navigation Towpath - running adjacent to the western edge of the Olympic Park - will be closed from just north of the International Broadcast Centre (at Eastway) to Stratford High Street from the 3rd July until the 10th September. The path will be closed using an anti-terrorism traffic regulation order requested by the Met Police and applied for by the London Borough of Newham. Diversion required: A diversion along "quiet roads" will be signed for use by both cyclists and walkers. According to Walk London, the plan is currently being finalised and an online version will be posted on the London2012 website soon. It'll have to be a twisted and fairly tedious diversion, by the looks of things.
» Boaters wishing to travel along the River Lee Navigation between Bow Locks and Lea Bridge Road will be required to pre-book passage during two daily navigation windows, from 6-9am and then from 7-9pm. That's pre-booked boats only, for two whole months. Both the Hertford Union Bottom Lock and Commercial Road Lock on the Regent's Canal will also be closed. [more]
Saturday 14th July
» Pudding Mill Lane DLR closes, because it's inside the boundary of the Olympic Park.
What won't close i) The Greenway between Stratford High Street and West Ham station (will be used by London 2012 spectators arriving by train, as part of the "Last Mile" network, and should also remain open for non ticket holders) (footbridge over Stratford High Street in operation) ii) At Eastway it will be possible to access the towpath and head north along the Lee Navigation using the ramp which will remain open. iii) The Hertford Union towpath, and the ramp from White Post Lane onto the Hertford Union towpath, will remain open. iv) At Stratford High Street it will be possible to use the new floating towpath underneath the Bow flyover (so that's a relief)
