begin by March 2023 and be operational by spring 2025. Extensions in planning North-South MetroLink Northside/Southside - St. Louis City This 5.6-mile (9 km) expansion would serve approximately 14 stations between Grand Boulevard in North St. Louis and Chippewa Street in South St. Louis running primarily on Jefferson Avenue. Proposed frequency is 10 to 20 minutes operating between 5 a.m. and 1 a.m., 7 days a week. It would provide a fixed rail upgrade to Metro's high-volume #11 (Chippewa) and #4 (Natural Bridge) bus routes. A Locally Preferred Alternative (LPA) is expected to be selected in the fall of 2022. St. Louis County Connector This extension would be a Phase II to Northside/Southside and continue from the North Grand Boulevard station along Natural Bridge Avenue toward North St. Louis County. Higher-volume bus stops further west along Metro's #4 (Natural Bridge) bus route support further expansion into North St. Louis County. Final routing, station location, etc. have yet to be determined for this segment. It is being studied by Bi-State and St. Louis County as of the summer of 2022. The North-South corridor will not feature the rapid transit like characteristics of the Red and Blue lines and will instead be similar to other on-street light rail lines in the US, such as Houston or Phoenix, and would be separate from the rest of the rail system. Because of this, an infill station to facilitate transfers will be constructed on the Red and Blue Lines where they intersect with the new Jefferson Avenue alignment. Previous extension proposals Many of these extensions were proposed when Metro released its Moving Transit Forward plan in 2010. Most are now defunct as regional leadership has said their current focus is on the City and North County corridors and not previous expansion proposals. North-South MetroLink Corridors NorthSide - Downtown to Florissant Valley Community College This extension would have run north from downtown St. Louis to the Florissant Valley Community College. A study for this extension was completed in 2008 and a Locally Preferred Alternative (LPA) was selected. The LPA would have begun in downtown St. Louis, traveling west on Delmar Boulevard to Jefferson Avenue, north on Jefferson to Natural Bridge Avenue then west on Natural Bridge to Goodfellow Boulevard. It would then travel north on Goodfellow to West Florissant Avenue and follow West Florissant to Florissant Valley Community College. See "Extensions in Planning" section for updated
