The Caldecott Tunnel's fourth bore is an SF Bay Area example of how long it infrastructure investment takes before tax payers can enjoy the benefits.
The Caldecott Tunnel in the East Bay had three "bores". The center bore would switch directions at noon to accommodate morning and afternoon rush hour, causing painful merges from four to two lanes for people driving the other direction.
Plans for adding a fourth bore, so there would be two eastbound and two westbound bores, started in 2000. Funding wasn't approved until 2007. Construction began in 2009 and the fourth bore opened to the public in 2013.

So 24 years and $6.5 billion to build (really fix) a 2 mile bridge. The entire original bridge (both spans, plus the Yerba Buena tunnel) cost less than $1.4 billion in 2013 dollars, and was built in around 3.5 years.
