for fast walkers to cross the street diagonally (even though the crosswalks are not marked as such). However, a growing number of traffic signals are being programmed to use a concurrent pedestrian phase. A similar situation exists in Cambridge, Massachusetts, where intersections with exclusive intervals can allow fast walkers to cross the street diagonally. In Washington, D.C., diagonal crossing existed at several downtown intersections until the mid-1980s. It was tried again on an experimental basis at 7th and H streets Northwest in the Chinatown neighborhood beginning May 2010. In 2017, a second Barnes Dance crosswalk was added at Irving and 14th streets Northwest. In New Haven, all of the intersections with traffic lights have implemented the pedestrian scramble, since at least 1974. In New York City, there were 635 intersections with exclusive pedestrian phases , although the majority were "T-away" intersections (T-intersections where the cross street takes traffic away from the intersection) and mid-block crossings, where a pedestrian scramble was one of the two phases. Many of the remaining 86 intersections with pedestrian scrambles are located where intersection geometry is skewed, requiring diagonal crossings from pedestrians and/or an exclusive pedestrian phase due to conflicts with vehicular traffic. Major pedestrian scrambles include the intersection of Vesey Street, Broadway, Park Row, and Ann Street in Lower Manhattan, as well as Nostrand Avenue and Flatbush Avenue in Midwood, Brooklyn. Signals at several intersections in Pittsburgh, including along Craig Street at Centre Avenue, Bayard Street, Fifth Avenue, and Forbes Avenue near the University of Pittsburgh; on Forbes at Morewood Street at the main entrance to Carnegie Mellon University; and on Forbes at Murray and Shady Avenues in Squirrel Hill stop traffic from all directions and allow pedestrians to cross in all directions. They are not, however, specially signed; they use a standard pedestrian crossing light (with added audio signal for the visually impaired). The signal at the intersection of McKinley and Riverside Avenues on the campus of Ball State University in Muncie, Indiana, is called the "Scramble Light" and is identified by the university as a campus landmark. Athens, Ohio, has one diagonal crosswalk still in place (as of May 2022) at the intersection of Court and Union Streets in Uptown, near the Ohio University campus. Some pedestrian scrambles are implemented only temporarily, during times when extremely high pedestrian traffic is expected. A notable example of this occurs on home-game Saturdays at the intersection
