Metro Transit began study of 11 corridors for their potential for bus rapid transit in 2011-2012 with the goal of opening the first BRT line in 2014. By 2012, Snelling Avenue and West Seventh Street were identified as the first two candidates for implementation. Limited stop bus operations on West Seventh Ave would have allowed BRT-style improvements to be more easily integrated. The corridor was initially identified as the second best candidate for upgrades with an opening in 2016 but work on the project was deferred so Ramsey County could study further transit options in the corridor. The title of METRO B Line was eventually given to the Lake Street-Marshall Avenue-Selby Avenue Corridor from Uptown, Minneapolis to downtown Saint Paul.
