People complain about the progress in this project. In 2008 Spurs announced the first plans to stay in the white hart lane area the initial capacity was to be 52,000, it took 11 years from the initial announcement to the ground being open, many years wasted due to problems with the planning applications numerous dealings with English Heritage, blues are going to have to be patient.
As for the accessibility there is definite scope for a Merseyrail extension which I think was in the pipelines before BMD was even mentioned? Also I don’t know any ITK information but with working in Sheffield there may be potential for a shared light rail (tram)/ road vehicle dock road from the city centre to BMD, depending how busy the road is with HGV’s these days. I just think these things are more likely to be considered once we have the the stamp from planning.
