It’s the ‘F’#@! line

Park Slope straphangers will soon be muttering the F-word over their shoddy subway line — again.

That’s because the beleaguered F line will be completely shut down in the trendy neighborhood for at least seven different weekends over the next 11 months. It’s the second time in the past year that the line has experienced closures.

Stroller-pushing mothers are already dreading more of the sardine-like cramming into replacement shuttle buses for the affected stops between Jay Street-Borough Hall and Church Avenue.

“People are going to totally freak out,” said yoga instructor Laura Stryjewski, 33. “Taking the shuttle is a royal pain . . . This is terrible news.”

The first two shutdowns are scheduled for Feb. 20-22, and Feb. 27-March 1.

Adding insult to injury, the G train will be completely shut down for those weekends, too.

The next five closure dates are subject to change but are scheduled for the weekends of May 8, May 15, May 22, Nov. 13 and Nov. 20 — with more coming in 2011, transit officials said.

Park Slope business owners are fearing a financial hit.

“This is pretty bad. It’s a big cut,” said Allyssa Lamb, 34, who owns Barbes, a bar that also serves as a “community center” on the corner of 9th Street and 6th Avenue. “People won’t be able to come in from Manhattan as easily.”

Transit officials blame the closures on the rehabilitation of the Culver Viaduct, a $179 million project that won’t be finished until 2012.

Sen. Daniel Squadron (D-Manhattan/Brooklyn) — who last year called for a full-scale review of the F line’s reputed sub-par service — said he’ll be watching to make sure the MTA widely advertises when the shut-downs will occur. “We’ll also make sure they’re running the right amount of buses,” he said. “We do need to fix the line, but the closures will always be a headache.”

It’s far from the first time the F line has drawn the ire of Park Slope residents.

A similar shutdown occurred during six weekends last year for the same project.

Residents complained then about not knowing which weekends were affected, which is why the MTA intends to release a definitive schedule this time around, officials said.

The MTA released a report at the end of last year saying the flailing line “lags behind other routes” in terms of keeping trains on time, experiencing 25 percent more delays than the system average.

Officials said they were working on a number of improvements, including using newer cars on the line.

Improvements are also being made to the tracks and signals to make trains run more reliably, said NYC Transit spokesman Charles Seaton.

But some riders were not convinced.

“They already put us through this six months ago,” said opera director Isabel Milenski, 37. “It’s like they’re not fixing the issue.”

“The shuttle rides are grotesque. It’s going to be chaotic.”

The skipped stations will be Bergen Street, Carroll Street, Smith-9th streets, 4th Avenue., 7th Avenue, 15th Street and Fort Hamilton Parkway.
