Closure of Constellation in Century City for Purple Line Extension work

UPDATE, September 18 – This closure is expected to begin Friday, September 21, 2018. 

UPDATE, July 25 – This closure has been postponed. During excavation and relocation of underground utilities, Metro contractors found extensive concrete causing delays.

Starting this week and into next week, onlookers will notice construction ramping up on Constellation Boulevard in Century City. The design-builder for Section 2 of the Purple Line Extension Transit Project, Tutor-Perini/O&G, will be removing trees, streetlights and abandoned oil lines on the south side of Constellation to make space for the launch box to support the tunnel boring machines.

Like constructing a station box, Tutor-Perini/O&G will have to pile, deck and then excavate Constellation at Century Park East to create the tunnel boring launch box. By June 15th, the design-builder expects to have a work zone with protective concrete barriers, fencing and sound blankets in place around the launch box area.

Because of the complexity of constructing a launch box, commuters can expect Constellation at Century Park East to be closed to through traffic for about 15 months.*

*Currently, the project is approved for a 9-month closure. The contractor is studying the possibility of a 6-month extension for a total of 15-months. Construction Relations will continue to notify the community of the schedule as we proceed.

During decking of the launch box, the street will be replaced with temporary concrete deck panels allowing traffic and access to driveways on Constellation Boulevard to be restored while excavation continues underneath to create space for the tunnel boring machines.

A community meeting will take place on Thursday, May 24, from 6:30 p.m. to 8 p.m at Century Park Towers, Conference Room A. To RSVP, click here.

The second section of the Purple Line Extension will extend the Purple Line 2.59 miles from Wilshire/La Cienega to stations at Wilshire/Rodeo and Century City/Constellation. Section 2 is forecast to begin operations in 2025. For more information visit

  1. I hope the headline one day reads “Underbudget and opening ahead of schedule.”

  2. Why Metro Ever Let Tutor-Perini have the Phase-2 Purple Line Contract they are the ones that Screwed Up the Redline and were thrown off that project
