Elon Musk’s The Boring Co. will present in-depth plans for a 2-mile freeway tunnel under city streets during a special City Council meeting Thursday. Council members will consider fees and terms for allowing construction from SpaceX headquarters west beneath 120th Street. Regulators are now reviewing design plans for hazards. The tunnel would be about 40 feet below ground and, ultimately, stretch to LAX. The meeting will start at 3 p.m. at City Hall, 4455 W. 126th St.
