Recent approval of a more than half-billion-dollar expansion of the Metro Gold Line light rail system could spell economic good news for the region, with transit officials predicting major job growth and an economic boon with nearly four years of planned construction associated with the commuter line’s growth.

In all, the Gold Line, which currently runs from Union Station in downtown Los Angeles to the eastern edge of Pasadena, will be extended 11.5 miles, with six new stops from Pasadena to Azusa.
