The Metropolitan Transportation Authority will hold eight open houses and City Council briefings in May on the proposed Gold Line extension that will go from East Los Angeles to either Whittier or South El Monte.

An environmental impact report on the two competing routes is expected to be released this summer.

Both possible routes would run from the current end of the Gold Line at Atlantic and Pomona boulevards and go along the 60 Freeway, but one route would go south on Garfield Avenue and east on Washington Boulevard, ending up at the Whittier campus of PIH Health Hospital near Lambert Road and Washington Boulevard. The other follows the 60 Freeway east to Peck Road, ending in South El Monte.

The open houses will be held 30 minutes before the city council meetings. Here’s a list of the times and meetings:

• Tuesday, 6 p.m.: Commerce City Hall, 2535 Commerce Way, Commerce.
