Place. An attempt was made in 1865 to change the name of Middle Street to Sterling Street, possibly for Lord Stirling, but was vetoed by Mayor Alfred M. Wood. Prospect Park's establishment required additional access, and in 1868 the New York Legislature passed an act that provided for Middle Street's renaming to Prospect Avenue and its widening from . Maps made in 1874 for the Kings County Town Survey Commission provided for a extension of Prospect Avenue into the Town of Flatbush; however, this was stymied by a steep, boulder-strewn terminal moraine, and the fact that the city of Brooklyn's and town of Flatbush's sections of the road were misaligned. In 1903, plans were approved to correct the misalignment; Prospect Avenue was extended through the cut, and Seely Street was placed over Prospect Avenue on a concrete-and-steel arch bridge. Co-named streets 16th Street is co-named "Captain Vincent E. Brunton Way" after a New York City Fire Department captain who died in the September 11 attacks. 10th Avenue is also co-named "John P. Devaney Boulevard" in this area after a firefighter who died while trying to rescue residents of a burning Red Hook building in 1989. Traffic circles Traffic circles are relatively rare in New York City, but Windsor Terrace has three of them, all framing Prospect Park entrances along the park's border. The northernmost, a medium-sized traffic circle named Bartel-Pritchard Square, is at the intersection of Prospect Park West, Prospect Park Southwest, and 15th Street, and contains an ornate entrance framed with two columns. Another traffic circle was built at Prospect Park Southwest and 16th Street, although it no longer operates as a circle. The southernmost, a large traffic circle named Park Circle, is at the convergence of Prospect Park Southwest, Coney Island Avenue, Parkside Avenue, Ocean Parkway, and Fort Hamilton Parkway, and was reconstructed in 2010. Park Circle's entrance to Prospect Park is designed in a style similar to the Bartel-Pritchard Square entrance.
