plans as of 2022. SouthSide - Downtown to Bayless This 9 to 17-mile (14-27 km) extension would run south from downtown St. Louis to Bayless at Interstate 55. A study for this extension was completed in 2008 and an LPA selected. The LPA begins at the Gateway Transportation Center at 14th Street & Spruce Street, continues south on 14th to Chouteau Avenue, then traveling west on Chouteau to Jefferson Avenue. It would then travel south on Jefferson to Meramec Street, where it would follow the Interstate 55 right-of-way to a terminus at Bayless Ave. Cross County Corridors Daniel Boone - Clayton to Maryland Heights/Westport & Chesterfield A study performed in 2000 recommended a new MetroLink line from Clayton, Missouri, to Westport Plaza in Maryland Heights, Missouri. The 8 to 10-mile (13-16 km) line would have run north from the Clayton station along the disused Terminal Railroad Association of St. Louis "Central Belt" right-of-way paralleling Interstate 170, then turn west to follow existing Union Pacific Railroad trackage operated by Central Midland Railway to Page Avenue where the line would have then followed Page to Westport Plaza. This proposed alignment would have added up to six stations between Clayton and Maryland Heights in the Interstate 170 and Page corridors serving Ladue, Olivette, and Overland. A extension to Chesterfield would have been a potential Phase II of the Daniel Boone Corridor. The alignment would have headed west from Westport Plaza and crossed over Interstate 270 in Maryland Heights. It would have then run along the Page Avenue Extension (Highway 364) until it turned towards Creve Coeur Lake Memorial Park. It then would have headed westward to Spirit of St. Louis Airport in the Chesterfield Valley. This alignment has not been given serious consideration because of its perceived low ridership potential. MetroNorth - Clayton to Florissant This extension would have extended the current Blue Line from Clayton towards North County and into Florissant, Missouri. Like the Daniel Boone line, some of it will follow along the old Terminal Railroad Association of St. Louis "Central Belt" right-of-way paralleling I-170. MetroSouth - Shrewsbury to Butler Hill This extension would have extended the current Blue Line from its terminus in Shrewsbury, Missouri, further into South County beyond Interstates 270/255 to Butler Hill Road. An environmental impact study was completed in 2004; however, selection of an LPA was deferred due to the lack of local funding sources as
