The Expo Line Construction Authority posted the above video last month and today has been sending the link around to interested parties.
I’ll throw in my two cents: My experience is that most roads are far, far louder than light rail lines. I live a mile from the 210 freeway and can often hear traffic on the road from my house. I’ve never heard anyone complain that they can hear light rail from a mile away.
Phase one of the Expo Line will run between downtown Los Angeles and Culver City; train and signal testing has been underway for the past couple of months. The second phase — funded by Measure R — will run between Culver City and downtown Santa Monica and is expected to begin construction later this year.
The Construction Authority is an independent agency that is constructing the project that will eventually be turned over to Metro to own and operate.
