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!
