But there is already some discussions of future extensions, like to North Beach, Fisherman's Wharf, and the Marina District.
as i was confused - it is only the currently-being-built extension to chinatown that's expected to open this year, not the further extensions.

Sorry if what I wrote was confusing. :(

The to-be-active part of the line currently goes out to Chinatown, though its tunnel was built out to North Beach for convenience in extracting the TBM's.

I perused Google Maps's satellite pictures of northern SF, and a lot of the streets there are only two-lane. The Central Subway line is being built under Columbus Ave., and the best possibility for getting to the Marina District is Bay St., with its four lanes. Lombard St. is also four lanes near the Marina District, but near Columbus Ave., it gets down to two lanes, and it even has a block where it is a wiggle.

Another delay announced today (Friday night news dump) - opening is now projected for the end of 2021. That means the odds are now good that the MBTA Green Line Extension will beat it to revenue service.

FWIW the date was already pushed back to June 2021 in September 2019: https://www.sfexaminer.com/news/its-off ... n-planned/

Here’s the news that was posted on Friday: https://www.sfmta.com/blog/central-subw ... e-end-2021. Unclear if the pandemic had a hand in these delays.

That last one is very interesting. The line's under-construction stations:
  • 4th and Brannan Station at 4th and Brannan streets (street level)
  • Yerba Buena/Moscone Station at 4th and Folsom streets (subway)
  • Union Square/Market Street Station on Stockton Street at Union Square (subway)
  • Chinatown Station at Stockton and Washington streets (subway)
A tailtrack tunnel was built northward in Stockton St., turning NW in Columbus St. and ending near Washington Square.

The highest-polling locations:
  • Columbus Ave. & Greenwich St. - 2330 - North Beach / Telegraph Hill
  • Columbus Ave. & Bay St. - 2216 - North Beach / Russian Hill
  • Van Ness Ave. & Chestnut St. - 1123 - Russian Hill
  • Fillmore St. & Bay St. - 992 - Marina District
There were several others nearby that ranged from 582 to 743, and several others scattered over NE SF with smaller numbers.

The highest-polling locations suggest a line that continues in Columbus St., then turns west in Bay St. until the Marina District.
