[SDCBC] Red Ball or Blue Ball False Dichotomy

Red Ball or Blue Ball False Dichotomy

Dear Friends,

CALTRANS is presenting you with a false dichotomy  it is not only a choice of an undercrossing or an overcrossing.  These guys always want to give you only two competing choices.

Does baby want the Red Ball or Blue Ball?  No maybe we want something else or have it all.  This is a multi billion dollar project.  The environment may demand an undercrossing which can also have a trail and path.  Bikes and walkers may be served by both .

Make sure you ask for the patrol car width or you will end up with a one lane narrow path.

All the best

  I'm with Wade--something rideable sooner is better than waiting for all the bells and whistles in ten years.

    To me it hinges on how vulnerable the undercrossing would be to
    extended closure from flooding.  I assume the bridge option will be
    much more expensive.

    Since either solution is probably many dollars and years from actually
    being implemented (along those lines, how long is it going to take
    Caltrans to restore the 50 meters of asphalt at the north end of SVR
    to make that section all-weather and less sketchy on narrow
    tires????....that's got to be going on 10 years or more now ), it
    seems to me lobbying for some relatively dirt cheap improvements to
    the current bike path terminus would make a lot of sense.

    A curb cut and some asphalt on the east side of ECR would accommodate
    entry from and exit to southbound ECR, and repaving of the ragged
    existing ramp (there's already a curb cut), and ideally, some
    realignment as to pitch and switchback angle of the ramp on the west
    side would improve that transition.  As I'm sure Serge would agree,
    it's not all that hard to get to SVR from there via El Camino Real and
    Carmel Valley Road.  Or, if you're ultimately headed south through
    Sorrento Valley, it's not that big a deal to just go on up ECR and
    turn right on Carmel Mountain, probably less arduous than a 7.7%
    bridge, and if you're going the other way (out Carmel Valley road to
    the beach), the 50 yards going past the park&ride you'd get on SVR
    isn't of much additional use compared to the aforementioned taking of
    ECR direct to Carmel Valley Road.   I realize the roadway transitions
    aren't necessarily practical for, say, kids on training wheels, but at
    this point SVR itself isn't much of a destination unless you're headed
    for a tour of the sewer pump station.

    I would hope that such obvious and inexpensive improvement to the
    current transitions wouldn't impede further consideration of extending
    the class 1 facility, but frankly even if it does I think it's worth
    it - those transitions are needed regardless of how they decide to
    deal with the freeway.
