NEW YORK (CBSNewYork) — It’s not the news Upper East Siders, who are sick and tired of the Second Avenue subway construction project, wanted to hear.

The $4 billion mega-project might not be completed until February 2018 — about 16 months later than the Metropolitan Transportation Authority had planned, according to a report from the Federal Transit Administration.

Agency spokesman Kevin Ortiz disagrees with the assessment saying, “A project of this magnitude does not come without risks.  We continue to work to mitigate those risks, adhere to the current schedule and keep the project on budget.”

Business owners along Second Avenue are fuming saying construction trucks, jackhammers and countless detours have been driving their customers elsewhere. 

Residents have said it has become a nightmare living on Second Avenue thanks to some of the odors and dust created by the construction.
