Route description

SR 109 begins at U.S. Route 101 in East Palo Alto. It continues north, paralleling the city border with Menlo Park before entering Menlo Park and crossing a railroad. SR 109 passes by salt evaporators before terminating at SR 84 just west of the Dumbarton Bridge. [1]

History

In April 1958, I-109 was proposed as a name for the route that is now Interstate 280. This proposal was rejected by AASHTO. [2] The California State Route 109 designation was first defined in 1963, running from Sunset Cliffs Boulevard to Interstate 5 in San Diego. In 1972, that route was deleted and was renumbered as a western extension of Interstate 8. Later in 1984, SR 109 was defined as a route in Palo Alto.

The segment in East Palo Alto between US 101 and Notre Dame Avenue remains in local control. Under Cal S&HC § 409 (b), the state will not take control over this section until Caltrans and the city determine that it is in an "acceptable state of repair".

Major intersections

Except where prefixed with a letter, postmiles were measured on the road as it was when the route was established, based on the alignment that existed at the time, and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers an overlap due to a correction or change, and T indicates postmiles classified as temporary (for a full list of prefixes, see California postmile § Official postmile definitions ). [2] Segments that remain unconstructed or have been relinquished to local control may be omitted. The entire route is in San Mateo County.
