free bike rentals. Additionally, since November 21, 2021, the University can be accessed by the San Diego Trolley. On that day, the existing Blue Line was extended north from Downtown San Diego to UC San Diego and the University City area. The extension gave the campus two trolley stations: UC San Diego Health La Jolla and UC San Diego Central Campus. A major goal of the project is to ease traffic and parking on campus while providing more accessible transportation to nearby areas. Construction began in 2016, with the line in service in November 2021. As part of UC San Diego's existing public transit partnerships, all students have unlimited access to MTS regional buses and trolleys, as well as most North County Transit District transportation services upon paying a "transportation fee" in registration. Construction Several facilities are currently under construction at the UC San Diego campus. The North Torrey Pines Living and Learning Neighborhood is completed, with students living in the completed facilities since Fall 2020. The Theatre District Living and Learning Neighborhood is scheduled to open in Fall 2023. There is also significant infrastructure construction, including the UC San Diego Central Campus Station and UC San Diego Health La Jolla trolley stations, which will be connected from campus to the Downtown San Diego area.
