>>1070973The 1.9mile long Regional Connector Line is currently under construction and will open in 2021. It connects the Blue and Expo Lines at 7th Street/Metro Center to the Gold Line at Little Tokyo/Arts District Station through a tunnel with 3 stations.
This project requires the at-grade Little Tokyo/Arts District Station to be relocated underground (listed as 1st Street/Central on the map).
It is expected that when the Regional Connector is open, the Expo Line will be discontinued and merged with the south leg of the Gold Line to Atlantic Station. The Blue Line will merge with the north leg of the Gold Line to APU/Citrus College Station. The former being called the Gold Line and the latter being called the Blue Line.
