After nearly a century, the MTA is repairing and modernizing subway stations around the city.

Work began Monday on the Grand Concourse and East 174th Street station.

Currently there is only one staircase closed, but that work is expected to ramp up in the coming weeks with the whole station shutting down on Aug. 13 as the MTA carries out a complete makeover.

Citnalta, one of the companies contracted to make structural repairs, is also working on modernizing the station with new turnstile areas, LED lighting and security cameras.

The MTA says the station has been operating since 1933, which means it has suffered a lot of wear and tear. Riders say it's easy to spot crumbling concrete ceilings and walls or missing tiles and rust.

The makeover is part of a multimillion-dollar project to rehabilitate three different station locations. The 174-175th Street station, the 145th Street station and the 167th Street station will all be repaired.

Frank Acuri, the project manager working at the East 174th Street station, tells News 12 the work at all three stations currently is part of a bigger plan that initially had eight groups of stations budgeted for repairs.

Acuri says it’s a tough job because lots of riders use the B and D lines to get to work, school and Yankee Stadium.

“What makes this so difficult is the aggressive schedule,” he says. “We have to work around the Yankees schedule, which no New Yorker wants to miss, but we have a deadline to hit.”

He says the completion goal date is Jan. 3.

The same work is being done at the 145th and 167th Street stations. The MTA urges riders to make use of the Bx1 and 2 buses while the station remains shut down.
