Summary
The Purple Line Extension design-build contractor for Section 2 is moving forward with construction activities in preparation of the construction staging area in Century City. In order to support excavation of the tunnel boring machine launch box, a full closure of Constellation Blvd. between Century Park East and Avenue of the Stars was put in place in September 2018. The closure will be in place until July 2020.* During the closure, public access will be prohibited to the driveway on the north side of Constellation Blvd. (behind Watt Plaza).
What to Expect
Constellation Bl at Century Park East will be closed to construct a launch box for the Purple Line Extension tunnel boring machines digging the twin tunnels for the underground subway through Century City.
Similar to constructing a station box, the design-builder will have to pile, deck, and then excavate to create the launch box. A work zone with protective concrete barriers, fencing, and sound blankets will be established to support the work.
During pile installation, 70- to 90-foot holes are augured into the streets along the perimeter of the launch box. After the piles are in place, the street and sidewalks are excavated and replaced with temporary concrete deck panels which will restore traffic and access to driveways while excavation continues underground to create space for the tunnel boring machines.
