north and 11218 to the south). In this area, Vanderbilt Street, named after John Vanderbilt, splits western Brooklyn's general street grid (comprising numbered avenues from 1st–101st Streets) and southeastern Brooklyn's general street grid (comprising lettered avenues from East 1st to East 108th Streets). Streets There are three streets between 16th and 17th Streets in the Windsor Terrace street grid, since the streets diverge from each other from Park Slope eastward. The northernmost of the streets is Windsor Place, which runs between 7th Avenue and Prospect Park Southwest. The southernmost of the streets is Prospect Avenue, which continues southward to Ocean Parkway (near the Fort Hamilton Parkway overpass across the Prospect Expressway) and northward to Third Avenue. Running between these two streets from 10th Avenue to Terrace Place, Sherman Street is named after Roger Sherman, a signatory of the Declaration of Colonial Rights, the United States Declaration of Independence, the Articles of Confederation, and the United States Constitution. The street name "Windsor Place" has been applied to two different streets throughout the neighborhood's history. The current Windsor Place was formerly Braxton Street before the 1900s, while 16th Street between Prospect Park W and Prospect Park SW was known as "Windsor Place" before then. Prospect Park West takes the place of 9th Avenue in the Windsor Terrace grid, and continues with the "Prospect Park West" name south of Prospect Park's borders, continuing southeastward to Green-Wood Cemetery, where it ends in a cul-de-sac. The stretch of Prospect Park West between 16th Street and Green-Wood Cemetery has always been called the same name as the stretch adjoining Prospect Park; the entire street was formerly and officially named 9th Avenue. Southeast of Prospect Park West, past Bartel-Pritchard Square, 15th Street becomes Prospect Park Southwest. The road bends noticeably between 11th Avenue and 16th Street; Prospect Park Southwest was previously known as Coney Island Avenue and originally known as the "Coney Island Plank Road" in the days of unpaved roads, when logs or "planks" were laid for stability and to keep the mud down. The southernmost stretch of Prospect Park Southwest, south of the bend at the termination of 16th Street, still retains Coney Island Avenue's street numbering system. Prospect Avenue extends from Hamilton Avenue to Ocean Parkway and is crossed by a bridge at Seely Street. The northern part was originally known as Middle Street and had its southernmost limit at what is now Terrace
