On Dec. 8, the project’s tunnel-boring machine broke through the ground at the Grand Avenue Arts/Bunker Hill Station at Second and Hope streets. The breakthrough follows months of digging from the Little Tokyo station at First Street and Central Avenue. According to Metro’s blog The Source, work went faster than in the first tunnel, digging 400 feet per week on average. The boring machine will now dig the last part of the tunnel, wrapping at Fourth and Flower streets at the end of January. The Regional Connector will create 1.9 miles of new tunnels and three new stations in Downtown Los Angeles, linking the Gold Line, Expo and Blue lines. Work is expected to finish in 2021.
