For about the last week the road route from LCY into Central London has been grossly congested, all the way back past LCY, due to the works now started for the new "Cycle Super Highway" along The Embankment. This morning was the worst, at 0900 it took about an extra hour. This even significantly impacts on journeys like LCY to Canary Wharf, because the congestion now reaches back this far.
How is the airport going to react to this significant reduction in their accessibility. The reduction in width along The Embankment and through the City of London to just one lane is part of the permanent scheme; it's not going to go away, and the resulting congestion suddenly reaches back for miles where it did not used to do so.
