Transport for London has issued the following update on progress with the Wonderpass works:-
"To date we have completed concrete crack repairs, floor resurfacing and drainage work, repaired leaks, started installing the electrics and framework to mount the new wall panels and lighting system and completed a trial installation of the cladding system. During the course of the floor surfacing works we discovered a section of subway floor supporting beams were in very poor condition. As these beams directly support pedestrian loading we must carry out strengthening and repair works to this section of the subway floor before the subway can be reopened.
In order to include these additional works we have had to extend our programme of works over the Christmas period. During this time the subway will remain closed as it's not yet in a safe condition to reopen to the public.
We now plan to reopen the subway in January. The changes will see the space being transformed into a 'Wonderpass'; a space that celebrates the local area, history and art, making the journey to cross Marylebone Road a more exciting experience for all users.
We apologise for the delay and extended inconvenience but hope you can appreciate the need for this additional work. We look forward to showing you the completed scheme soon."
