BIK LAN

Reacting to several tragic accidents on California State Highway 9 between the towns of Saratoga and Los Gatos, funds were found for critical safety improvements. Bike lanes have been in place for a couple of years; more recently, a few sidewalk segments have been introduced.

While I am happy that accommodations are being made for pedestrians, these should not come at the expense of cyclist safety. The bike lane is slowly disappearing: swallowed by the hillside in one section, obliterated by the new sidewalk in others.

More frightening than the narrowed bike lane is the new curb that separates the sidewalk from the bike lane: both are formed of black asphalt. The construction signs and cones have been gone for some time; can it be possible that they have no intention of painting the curb, or at least the sloped, leading edge of the curb at intersections? This is an accident waiting to happen. It seems just a matter of time before a cyclist runs into the curb and crashes—unable to see the curb at night, or having been intimidated to the far right of the narrow bike lane by fast-moving traffic.

Having explored the relevant section of the California Highway Design Manual, it seems clear to me that this (Class II) Bike Lane no longer complies with the standards.

The speed limit on this section of the highway is 40 mph or less; Section 301.2 states that the minimum width of the bike lane should be four feet. The width can be reduced to three feet if there is an adjacent concrete curb and gutter. There is certainly no gutter (which would effectively widen the available lane for bikes), so the bike lane should still be four feet wide. [It is not.]

The speed limit is 45 mph on the section of road where the hillside is overtaking the bike lane; per Section 301.2, the minimum width of the bike lane there should be six feet (!). [I assure you that you will not need a measuring tape to see that it is not.]

Of course, I am not a highway design engineer, so what do I know?

  1. That's definitely a bike lane FAIL. You can try writing an email to the city's public works department with the photo and pretty much say what you wrote here.

    Is it the bike lane in Saratoga or Los Gatos?

  2. It's in Monte Sereno, but it's along a state highway. I'm not sure whether the town or Caltrans is responsible, but I will send a letter to both (with photos).

  3. You're right it's probably Caltrans. Let me know how it goes.
