When is the earliest the Purple Line Extension will open?
Metro CEO Phil Washington has said that the agency is aiming to open the entire project to Westwood by 2024 — in time for a potential Los Angeles Summer Olympics.
Section 1 of the project is under construction and will extend the subway 3.9 miles from its current terminus at Wilshire/Western to Wilshire and La Cienega boulevards (with stations at Wilshire/La Brea, Wilshire/Fairfax and Wilshire/La Cienega).
Metro just gave the ‘notice to proceed‘ for section 2 of the project that will extend the subway another 2.6 miles to Century City with stations at Wilshire/Rodeo and Avenue of the Stars and Constellation Boulevard. The agency is also working on securing the federal funding that will be matched with local funds to build section three to Westwood.
What is jet grouting?
Jet grouting reinforces and strengthens the soil with concrete to support tunneling and cross-passage construction. Jet grouting at Wilshire/Western will be completed this month.
How many cubic yards of soil has been excavated at Wilshire/La Brea so far?
Approximately, 60,000 cubic yards at the Wilshire/La Brea station — that’s a little over 1,385 shipping containers full of soil. A typical shipping container volume is 1,169 cubic feet or approximately 43.30 cubic yards. The contractor, Skanka-Traylor-Shea, has a number of approved facilities around our region to receive the soil. Metro encourages recycling or reuse of excavated soil when possible.
What is decking?
Decking replaces the street and sidewalk with temporary concrete deck panels. The temporary surface allows construction to continue underground while traffic continues to flow while maintaining access to sidewalks and driveways. Decking has been completed for Wilshire/La Brea Station and is currently underway for the Wilshire/Fairfax station with completion on track to be completed in early June.
Will the piles currently being installed at Wilshire/La Cienega be removed when the station is complete?
During pile installation, 70 to 90 foot holes are augured along the perimeter of the station box. The piles, inserted into those holes, become a permanent part of the station structure.
