Grand Boulevard is a major, seven to five-lane wide, north-south thoroughfare that runs through the center of St. Louis, Missouri. It runs north through Carondelet Park in the south portion of the city to the Mississippi River north of the McKinley Bridge, about midway between Forest Park and the Mississippi River. Neighborhoods that it runs through include Dutchtown, Tower Grove East, Tower Grove South, Compton Heights, Tiffany, Midtown, Jef-Vander-Lou, Fairground, and College Hill.
Grand Boulevard connects with the St. Louis Metrolink light rail service at Grand Station. The station was closed in spring 2011 due to demolition and replacement of the viaduct on Grand spanning the Metrolink tracks, industrial train tracks, and an industrial park. The project is expected to take 18-24 months and will include the replacement of the Grand Avenue station. As of August 20, 2012, the new larger metro and bus station and viaduct with wider pedestrian sidewalks is open.
Grand Blvd also has the 70 Grand MetroBus, the busiest bus route in the St. Louis area. The route number comes from a streetcar line that previously operated on track in the center lane of Grand Boulevard with that number.
