Vision42 has been campaigning for this along 42nd Street for 20+ years. The video below shows how light rail, bus, and autos can all use a transit mall (from Portland). With an aging subway infrastructure and some of the slowest bus routes in the nation, would dedicated light rail routes be the next logical step for NYC? $3.6 million for the 2nd avenue subway would actually support the cost of installing light rail along 1st avenue (to 125th street) and back down 2nd avenue (to 42nd). Then could complete a two-way square around 34th to 42nd street. Is this the way the city should be thinking?
