Changes to parking in Farmingdale are in effect ahead of the Ryder Cup this week.

Here's what you need to know:

The Metropolitan Transportation Authority is expecting up to 18,000 golf fans to use the Long Island Rail Road to get to the tournament each day this week.

In response, the transit agency added extra train service to the Farmingdale Station to accommodate all those visitors.

From Tuesday, Sept. 23, to Friday, Sept. 26, the MTA added eight extra eastbound trains and one extra westbound train. There are nine extra eastbound trains on both Saturday and Sunday.

The PGA is offering a 15-minute complimentary shuttle from the Farmingdale station to the main entrance at Bethpage State Park. As a result, there is no parking available in either commuter lot for the duration of the tournament. The lot has been closed off and barriers set up for the shuttles.

Commuter lots officially closed on Sept. 18 and will reopen on Monday, Sept. 29.

MTA officials encouraged Farmingdale commuters to use the Wyandanch station, which is about 15 minutes away. Farmingdale parking permit holders can park in the garage adjacent to the Wyandanch station at no additional charge and will not have to pay extra for the zone change.

Fans who travel by car must park at Jones Beach and then board shuttle buses to the golf course. For spectators attending the whole week, they can buy the Long Island Rail Road's special event ticket, which is good during the Ryder Cup period for unlimited travel systemwide and to and from Farmingdale for $175. The special event ticket is only sold at ticket windows and ticket machines by selecting “MTA Away Deals."

Ryder Cup attendees cannot park in municipal lots in the village of Farmingdale starting at 4 a.m. on Tuesday, Sept. 23. The parking restrictions continue through Sunday, Sept. 28, at 4 p.m.

Municipal village parking is limited to commuters who have permits that have been displaced from the Long Island Rail Road lot, employees with permits and the general public for up to three hours.

The village is trying to strike a balance between accommodating residents, commuters and businesses while not allowing visitors to take up long-term spots without being downtown.

The village authorized a $500 fine within the downtown business district to keep parking available for customers.

Village officials are expected to join Nassau County Executive Bruce Blakeman downtown at 11 a.m. to discuss the benefits that the golf event is expected to have on local businesses this week.
