Fun with Highways: California Highway 114 (?)

I find myself on US 101 at least once a week for work, heading south from San Francisco to Palo Alto. A couple of weeks ago a started noticing a new route marker in a construction zone near East Palo Alto for Highway 114.

Highway 114? I did know there was such a thing. It turns out it is in fact a define short route along Willow Road between 101 and CA 84, leading to the Dumbarton Bridge, as described at cahighways.org.  It is only about one mile long.

I was also not familiar with 109, which runs along University Avenue in East Palo Alto but is unsigned.

So I wonder why 114 suddenly became signed as a detour route during this construction project? Is it perhaps a legal requirement, or maybe it will be signed in the future?

  1. Hard to know what the officials have in mind .
    Maybe they just like to keep people on their toes ;)
    A short time ago you commented on a lens I had.
    It is a Nikkor 18-200mm VR II. It is very convenient as it
    covers a nice range and you don,t have to change lenses,
    to get the zoom. It has gotten good reviews and is not bulky
    It costs more,but the convenience is worth it :)
