The Gateway to Major Freeways

Advance freeway entrance sign for I-80 and US 101 at Octavia Boulevard in San Francisco (2005)

While, technically speaking, this part of the Central Freeway isn't US 101, a point of some controversy among those who keep track of such things, it provides access to US 101 going south toward San Jose, and to Interstate 80 going east to Oakland.

One presumes that no directional designation is given for Interstate 80 because it's not possible to go west on Interstate 80 from this point, for obvious reasons: Interstate 80 technically begins where US 101 splits from the main freeway.

This photo was taken September 24, 2005, two weeks after Octavia Boulevard opened for traffic.
