The MnPASS lanes along Interstate 35W south of downtown Minneapolis were opened in stages between 2009 and 2011 and are a combination of new construction (south of Burnsville Parkway), conversion of the previously existing high-occupancy vehicle lanes (between Burnsville Parkway and 66th Street), construction related to the Crosstown Commons project, and conversion of a median shoulder into a priced dynamic shoulder lane. The lanes are concurrent-flow lanes using the inside/left lane in each direction. The northbound MnPASS lane begins at County Road 42 and extends continuously to 26th Street. The southbound MnPASS Lane begins just south of 42nd Street and extends to Cliff Road.
