Subway riders who have been waiting for a new No. 7 line station on the Far West Side of Manhattan for years will have to wait at least a little longer.

The opening of the station, once planned for the end of 2013, is now likely to be pushed back until July, officials said on Monday at a board meeting for the Metropolitan Transportation Authority. Already delayed by the complexities of the station’s custom-made diagonal elevator, officials say their biggest remaining obstacle is to finish testing of the communications system and fire alarm.

Most of the construction work for the station, at 34th Street and 11th Avenue, is done, the vice president for the authority’s capital construction company, Anthony D’Amico, said as he showed board members glossy new images of the station’s lobby with a colorful mosaic overhead.

“If you walk through the station today, you will encounter a massive three-level structure beautifully done with the utmost attention to quality and detail,” he said.
