In early morning hours of a cool winter morning, 20 concrete mixer trucks have arrived at the future Grand Av Arts/Bunker Hill Station in downtown Los Angeles.
It was the first major concrete slab pour for the new station’s concourse level and crews were preparing to place 185 cubic yards of concrete 70 feet below the surface. New footage from the construction site shows how crews worked quickly to pour, level and then finish the ubiquitous building material before it sets and hardens.
It will take approximately 24 hours for the concrete to harden and several days to fully cure. The rest of the concourse level slab will be poured in the coming weeks and crews will also begin to build the wall located on the north side of the station’s track level.
The station, at 2nd and Hope, is part of the Regional Connector project that is tying together the Blue, Expo and Gold Lines via 1.9-mile twin tunnels in DTLA. The tunnel will allow trains from Azusa, East Los Angeles, Long Beach and Santa Monica to run to and through DTLA, greatly reducing the need to transfer for those using Metro’s light rail trains.
