the highway, the alignment would begin its transition underground through the "west tunnel portal", passing under Hord Street near the Dallas World Aquarium and remaining underground for its duration. The alignment continues south under Griffin Street and between San Jacinto Avenue and Elm Street, an underground station, Metro Center station, would be located providing access for transfers to buses at DART's West Transfer Center or access to the Red and Blue Lines at West End and Akard stations. After crossing under Main Street, the alignment would turn east under the Belo Garden and continue under Commerce Street. While under Commerce Street, a second underground station, Commerce Street station, would be located between Akard Street and Ervay Street. Before passing under South Pearl Street, the alignment would begin to turn northeast, crossing diagonally underneath existing buildings and structures. A third underground station, CBD East station, located between Main Street and Elm Street would provide access for transfers to additional buses at DART's East Transfer Center. The alignment would continue traveling in a northeasterly direction before surfacing near the portal of the existing light rail tunnel under Cityplace. Station listing The project will include four new DART stations: one at-grade, and three underground which will consist of center platforms and introduce fare barriers. From west to east, the stations are: Museum Way, located southwest of the Perot Museum and north of Woodall Rodgers Freeway. The station will consist of side platforms. Metro Center, located under North Griffin Street between San Jacinto and Elm Streets and would contain a mezzanine level, a public concourse level, and a center platform level accessible from up to four street-level entrances. A headhouse located at DART's West Transfer Center would be the primary entrance for passengers. Commerce, located under Commerce Street near AT&T’s headquarters, and the Magnolia and Adolphus hotels. The primary entrance for the station would consist of a station building at Pegasus Plaza located at the southeast corner of Main Street and Akard Street as well as access from two additional street-level entrances. CBD East, located between Main and Elm streets just east of South Pearl Street. The primary entrance for the station would be a headhouse at Elm Street and South Pearl Street as well as access from an additional street-level entrance.
