The Los Angeles County Metropolitan Transportation Authority (Metro) in 2017 "nearly completed" mining twin tunnels for the Regional Connector light-rail project, agency officials announced in a blog post.
The tunnels run from the city's Little Tokyo neighborhood to the financial district, according to the post summarizing progress on the project. Each tunnel measures about 5,700 feet in length and is made of 1,140 pre-cast concrete rings.
