San Diego Mid-Coast Trolley Extension:
Committed to building it: 2010 (“The project was adopted into the …plan in October 2010.” Federal Transportation Authority.) -- Not sure how to account for the prior work.
Normal riders riding it: November 2021 (Wikipedia cites a local media outlet.)
Predicted Cost: $2.1 billion (per the aforementioned Federal Transportation Authority document from 2015).
