We can't possibly get any more excited about this than Brownstoner, which has already decreed it the "most momentous news in the history of time," but here it is: the Atlantic StationLIRR terminal entrance is supposed to open next week. That would be this thing, which was originally slated to be finished in 2007 after about 156 years of construction. Above: the plans versus the result. Brownstoner also reports that there'll be a completion ceremony inside the terminal tomorrow. All in all, it's been a big week already for Bruce Ratner: first the bonds for the Atlantic Yards basketball arena sell out, and now Long Islanders will be able to get there in style if the thing gets built.
