leaving the tunnel, the line passes below the Vista Bridge and enters downtown Portland, continuing along Southwest Jefferson Street before turning north onto the median of Southwest 18th Avenue. Near Providence Park, the tracks diverge eastbound onto Southwest Yamhill Street and westbound onto Southwest Morrison Street, crossing the Portland Transit Mall near the Pioneer Courthouse and Pioneer Courthouse Square. The tracks reconnect on Southwest 1st Avenue and head north, traversing the Willamette River via the Steel Bridge into the Rose Quarter. The line runs along Holladay Street in the Rose Quarter and the Lloyd District, passing the Moda Center and the Oregon Convention Center. It enters its grade-separated segment along the north bank of the Banfield Freeway at Sullivan's Gulch. The line then travels over the Interstate 84 and Interstate 205 interchange towards Gateway/Northeast 99th Avenue Transit Center. From Gateway Transit Center, tracks head south along the east side of I-205. A single-track junction south of Gateway Transit Center marks the start of the Airport MAX segment while a double junction south of Southeast Glisan Street splits into the I-205 MAX. The Blue Line turns east and enters the median of East Burnside Street at East 97th Avenue. At Ruby Junction/East 197th Avenue station, the line leaves the street and heads southeastwards until it reaches Cleveland Avenue station, its last stop, near the corner of Northeast Cleveland Avenue and Northeast 8th Street in Gresham. The Blue Line shares much of its alignment with the Red Line. Between 2001 and 2003, they used the same tracks from the 11th Avenue loop tracks in downtown Portland to Gateway Transit Center, where Red Line trains diverge towards Portland International Airport. Since 2003, they have shared the same route between Beaverton Transit Center and Gateway Transit Center. The Green Line joined a part of this shared alignment in 2009, entering from the Portland Transit Mall just west of the Steel Bridge, diverging at Gateway Transit Center, and continuing south towards Clackamas. Stations The Blue Line serves 48 stations. The 27 stations built as part of the inaugural line between Gresham and downtown Portland opened on September 5, 1986.
