New York seemingly has a traffic signal on every corner
. To improve safety at one Bronx intersection, DOT is going with something different: a roundabout.
The proposal is part of a larger road diet for Intervale Avenue in Longwood [PDF]. The plan was supported by a Bronx Community Board 2 committee in a 7-1 vote earlier this month.
Currently, the intersection of Intervale and Dawson Street, at the northern end of Rainey Park, is wide-open, with only a painted triangle in the middle to break up the expanse. People walking on the western side of Intervale have to cross 200 feet of asphalt.
“For years, we’ve asked for DOT to install a sidewalk there,” said CB 2 district manager Rafael Salamanca, Jr. “A lot of cars, they do illegal activities there that put lives at risk.”
Roundabouts — not to be confused with rotaries, their larger, faster cousins — have a lot of benefits. They slow down traffic at intersections and compel drivers to negotiate the right of way with other road users, instead of rote reliance on a traffic signal. They also save drivers time, instead of holding them at red lights.

Roundabouts should be designed with walking and biking in mind, too. On that count, the Intervale Avenue proposal is a huge step up from what’s there today.
The plan would convert Dawson Street from one-way to two-way and add “splitter islands” to both divide traffic as it approaches the roundabout and give refuge to pedestrians. On the north side of the roundabout, the splitter island is actually a wide median that extends for the entire block and through the crosswalk at East 163rd Street.
Two painted curb extensions would be added to crosswalks where north-south traffic from Intervale enters the roundabout. Drivers would pass the crosswalk before approaching “yield” markings at the roundabout itself. In an unusual design choice, the roundabout includes parking along its outer edges. The plan still calls for the removal of a few parking spaces.
Although about two of three of neighborhood households are car-free, parking is usually a top concern at the community board, Salamanca said. In this case, safety came first. “This intersection of Intervale and Dawson has been so stressful [to cross],” he said. “We as a community are okay with four parking spaces being taken to improve the safety of the community and the kids going to the park.”
