in december. some people are skeptical about this project, but musk and the boring company have both come out and said that the tunnel will open on december 10, 2018.
los angeles traffic has a tendency to be horrible, but musk thinks and hopes that this tunnel will be able to relieve some of the pressure off of traffic now and in the future. the construction does take a decent amount of time to complete, but could very well be a good alternative to sitting in traffic for hours, wasting gas, and being late to work.
