The MTA has released its revised service reduction plan, and for bus riders in Brownstone Brooklyn and beyond, the results aren’t pretty.

Despite opposition from elected officials, the MTA plans to “restructure” local bus service in the neighborhoods of Downtown Brooklyn, Carroll Gardens, Cobble Hill, Red Hook, Park Slope, Prospect Heights, and elsewhere, eliminating or reconfiguring several key bus routes.

Under the plan the B71, which runs east-west between the Columbia Street Waterfront District and Crown Heights, would be discontinued entirely.

The B61 and B77 buses would be combined into a single route running from Downtown Brooklyn to Windsor Terrace, through Red Hook.

Service on the B75, which runs north-south between Downtown Brooklyn and South Park Slope, would be replaced by an extension of the B57 on the northern portion of the route and the newly-combined B61/B77 bus line on its southern portion.

Weekend service on the B69 south of Grand Army Plaza would be discontinued. Instead, the bus would be rerouted to run along the B67 line, which travels south through Park Slope and ends in Kensington.

In all, the changes would affect 4,590 weekday and weekend bus riders, according to a tally of MTA estimates. (The transit authority did not specify if the number of affected riders were regular customers, annual riders, etc.)

The restructuring, aimed to help plug a $400 million budget gap, would produce a net annual savings of $3 million, according to MTA estimates.

Opponents of the cuts gathered on the corner of Smith and Union streets in Carroll Gardens January 22 to demand their buses be spared from the chopping block.

“There’s no denying we’re going through tough financial times,” said Assemblywoman Joan Millman, who organized the rally, but “we know the economy is going to get better [eventually] so why cut us off at the knees?”

Millman said the MTA has several other cost-cutting options besides reducing services, such as selling its building at 370 Jay Street and other valuable real estate assets.

State Senator Daniel Squadron said that eliminating the B71 would sever an important link between neighborhoods like Carroll Gardens and Park Slope and those on the eastern side of Prospect Park.

The B71 “is the true connector for a lot of [people] as you head east into Brooklyn,” Squadron said. “It really is the only route.”

Celia Cacace, a longtime Carroll Gardens resident, said the service cuts and reconfigurations would limit the mobility of seniors who count on buses to get around.

Others pointed to buses as useful means of transportation for students in the area and people who ride them to Downtown Brooklyn to shop.

“Buses are absolutely essential,” Councilman Brad Lander said. “The cuts they’re proposing are really unacceptable across the board.”

In releasing the revised service cuts, the MTA also announced a series of public hearings on the matter to be held at seven locations in New York City, Westchester, and Long Island in mid-March.

The Brooklyn hearing will begin at 6 p.m. on March 3 in the Beaux-Arts Court of the Brooklyn Museum, located at 200 Eastern Parkway in Crown Heights.

To get there the MTA recommends taking (among other trains and buses) the same B71 bus it plans to eliminate.
