Here are some new photos of the Regional Connector construction happening in Little Tokyo. Most of the construction activities this summer have been centered around preparing for the launch of the tunnel boring machine this fall.
Crews at the 1st/Central Station site have reached the bottom of excavation and work to build the station floor, or invert slab, is now underway. In the photos above you can see some of the struts used to brace opposing walls against each other. This type of excavation support system is best suited for narrow dig sites.
Underneath the intersection at Alameda and 1st Street crews continue utility relocation work and tunneling. To date, crews have reached about 45 feet below street level at the station site!
Will the 1st/Central Station have a mezzainne?
Sort of. The “mezzanine” will be in a building at street level, with escalators then going down to the platform:

Keep coming with those photos, Metro!
I’m surprised that the TBM launching slab will only be about 45 feet down, as there are several buildings to be tunneled under before 2nd Street is reached.
I heartily agree with Sean Kelly, its about time we get back on track with where we left off. Its time to pick up the pace and join the rest of the worlds greatest cities who all have advanced commuter light rail/subway systems. Don’t let any of the naysayers get in the way! Keep moving forward with the good work. Many people don’t realize if this isn’t done now, we are headed for total metropolitan gridlock!
And lets get TRUE HIGH SPEED RAIL in the U.S., Europe and Asia have succeeded at it for years! This is the 21st century for crying out loud, lets fulfill the vision!
Dear LA Metro,
I’m on the other side of the World but I think it is a great step forward that the isolated sections of your rebuilt transit system are going to be connected. Your task is significant, but in time you WILL provide LA with a comprehensive light rail and subway system.
I don’t thing all Los Angelinos fully appreciate what a major undertaking it is to reinstate a rail network when it has been removed for 50 years. Funding, planning, environmental laws, scope of works, finding corridors, working within those tight funding parameters etc.
Good job LA Metro!
