Metro narrowing route options for rail line from Union Station to Artesia
The Measure M sales tax increase approved by Los Angeles County voters last year will fund a massive expansion of rail in the county. This week, Metro will move forward with two of those projects.
The Metro board is winnowing down route options for two new train lines: One to push transit deeper into the eastern part of the county by extending the Gold Line from Atlantic Boulevard in East Los Angeles to South El Monte or Whittier. The other will connect Union Station with Artesia.
