      Switching from the subject of the bus yard path, back to the dam
      crossing:

      It seems clear that DCR will be examining all options for the
      crossing, not just the low cost option that our group has been
      advocating:

      1) Elevated bridge, using dam for the pier footings (this option is
      favored by the current dam operators)

      2) At-grade crossing over modified locks.

      3) Separate bridge, just upstream, with a drawbridge element.

      4) Do nothing. Or open for special events only.


      I propose a new option, that is a blend of the options above:

      4) For the two small locks, build the crossing on top of the lock
      gates, as we have discussed.

      For the one large lock, instead build a pedestrian drawbridge. This
      will free up the large lock for use during flood control operations.
      The ped drawbridge will be raised ONLY when a boat uses the large
      lock, and then ONLY if that boat is both LONGER and TALLER than the
      bridge can accomodate.

      (A short but tall boat will still fit on one side of the bridge, until
      the water level is normalized).

      =================================================================
      Someone with knowelge of the type of boats that go through the locks.
      How often would a TALL boat need the LARGE lock?
