  This paper is devoted to higher dimensional Anosov flows and consists of two
parts. In the first part, we investigate fiberwise Anosov flows on affine torus
bundles which fiber over 3-dimensional Anosov flows. We provide a dichotomy
result for such flows --- they are either suspensions of Anosov diffeomorphisms
or the stable and unstable distributions have equal dimensions.
  In the second part, we give a new surgery type construction of Anosov flows,
which yields non-transitive Anosov flows in all odd dimensions.
