The 7 train extension won't meet its projected opening date.
It's slated to open in June, but according to Metropolitan Transportation Authority documents, the $2.4 billion extension from Times Square to 34th Street won't open until late summer or early fall.
A progress report, which will be presented to an MTA committee on Monday, says that issues concerning escalators will push back the opening.
According to the MTA's website, the project reached 90 percent completion back in August.
The city paid for the extension, and Mayor Michael Bloomberg took a ceremonial ride from Times Square into the new station just before leaving office.
