The Crenshaw/LAX Transit Project is moving forward in December with construction of the three underground stations, the six bridges and two underground, cut-and-cover segments underway. In Inglewood, work on the right-of-way, a pedestrian underpass and the aerial Aviation/Century station are now under construction.
The 8.5-mile Crenshaw/LAX Line is a $2.058 billion light-rail line that will connect the Green Line and the Expo Line. It will have eight new stations to serve the Crenshaw, Inglewood and LAX communities. It is expected to open in 2019. The project is largely funded by Measure R, the half-cent sales tax increase approved by Los Angeles County voters in 2008.
The contractor Walsh/Shea Corridor Contractors (WSCC) continues building the base for the concrete floor and installing waterproofing as well as conduits and plumbing.
Metro is preparing for lowering of the tunnel boring machine (TBM) with a ceremony to be held in January to mark this milestone. Prizes will be awarded to kids that participated in the contest to name the TBM and draw the art work to be displayed on the side of the digging machine.
Soil treatment work for the cross passages is expected to be completed in December. Cross passages are short tunnels that will connect the northbound and southbound subway tunnels in case of an emergency.
Excavation to install the third level of bracing continues and will reach 65 feet below street level in the weeks ahead.
Excavation to the second level of bracing is expected to be completed in December.
Leimert Park Station (south portal)
Decking from Vernon Avenue to just north of 48th Street was completed on Nov. 24. Now the excavation work will continue under the concrete decking with traffic on Crenshaw moving overhead.
