After five years of construction, Mayor Bloomberg inaugurated the newest stretch of the Number 7 Subway Extension, running from Times Square to 10th Avenue and West 34th Street. The subway was a priority transit goal and will join Hell’s Kitchen and the Hudson Yards to midtown. Although the extension will not open to the public until mid-2014, the mayor rode the 7 on Friday, December 20 as part of operations testing.
