Riverside Drive is getting a road diet and a 25 mph speed limit, but bike lanes? Fuhgeddaboudit. Image: DOT [PDF]
Last night, DOT presented a plan to the Manhattan Community Board 9 transportation committee that would bring pedestrian safety improvements and a road diet to Riverside Drive, but DOT is proposing no bike lanes for the popular cycling route [PDF
The plan for Riverside Drive stretches from 116th to 135th Streets, which ranks in the top third of high-crash Manhattan corridors and was the site of 20 serious injuries from 2008 to 2012. Of those injuries, 19 were motor vehicle occupants and one was a pedestrian.
The average midday speed on the Riverside Drive viaduct in West Harlem is 36.5 miles per hour, according to DOT, with 75 percent of all drivers exceeding the street’s current 30 mph limit. Council Members Mark Levine and Helen Rosenthal asked DOT last month to lower the speed limit on Riverside to the new citywide default of 25 mph [PDF]. The agency said last night that the speed limit on all of Riverside Drive will soon drop to 25 mph, with signals retimed to match the change.
The project also includes two blocks of 116th and 120th Streets between Riverside and Broadway. East of Broadway, 120th Street is already one lane in each direction and 116th Street is a pedestrian walkway on the Columbia University campus. Due to low traffic volumes, those two east-west streets will receive road diets, dropping them from two lanes in each direction to three, including a center turning lane with pedestrian safety islands. The road diet includes an extra-wide parking lane to provide breathing room for cyclists, but no bike lanes.
On 120th, four refuge islands would be installed — one each at Riverside and Broadway, plus two at Claremont Avenue — while on 116th, just two refuge islands would be installed at Riverside and Broadway, with none at Claremont to accommodate trucks that would be unable to turn around them.
An audience member suggested closing the curved “slip lane” from Claremont Avenue to 116th Street, but DOT said that roadwork would exceed the project’s budget. Instead, the department is proposing adding a sidewalk and parking to the eastern side of the triangle at 116th and Claremont. Parking would also be added to the southern side, though some residents worried it might impact visibility for drivers going from Claremont to 116th.
The plan as currently designed results in a net gain of six parking spaces, but some community board members wanted more. “We need to be finding extra spaces to take care of people who are not well enough off to have a garage and the luxury of a garage,” said CB 9 member Ted Kovaleff, who asked that DOT add angled parking to 116th and 120th Streets to squeeze in more cars. DOT project manager Dan Wagner explained that adding diagonal parking would mean there wouldn’t be space for pedestrian islands.
“Do you prefer more parking or do you prefer pedestrian safety? I think that’s the debate,” Wagner said.
