Advocates to vent fury at Blaz gym

MAYOR DE BLASIO may get the sweats before he even gets to his Tuesday morning workout. Traffic safety advocates are planning to picket the mayor outside the YMCA at 8:30 a.m. near the scene of a crash Monday that left a 4-year-old girl and 1-year-old boy dead and a pregnant woman critically injured. Another woman was also injured in the accident.

The corridor — a wide two-way street lined with businesses — has been notorious in the neighborhood for years for drivers speeding and making quick, sharp turns, TV producer and street safety advocate Doug Gordon said.

“It’s a neighborhood street that seems to have almost like a highway running through it,” he said.

The community had been calling for better safety measures on the street.

“This was a completely predictable tragedy,” Gordon, a father of two, said. “We’ve been saying this is happening and it’s going to keep happening until the city fixes it.”

The news of the deaths at Ninth St. and Fifth Ave. rattled Park Slope, Brooklyn, where de Blasio had lived and still owns property.

“We’re going to evaluate and take action,” the mayor told NY1. “We don’t have any evidence yet that this crash was because of any factor in the way that the intersection was built.”

There have been more than 100 traffic injuries on Ninth St., from Prospect Park to Second Ave., between 2014 and 2017, according to city records.

A pedestrian was killed at the Ninth St. and Fifth Ave. intersection in February 2016.

Advocates called for trafficcalming measures, but City Councilman Brad Lander, who represents the area, said nothing would have prevented Monday’s death.“No intersection design was going to stop this erratic driver from killing these kids,” Lander said.

At noon, Transportation Alternatives and Families for Safe Streets will rally at City Hall to push for quick, low-cost fixes, such as painting markings and installing bollards when streets are resurfaced.
