  We study the conductivity of two-dimensional interacting electrons on the
half-filled $N$th Landau level with $N \gg 1$ in the presence of the quenched
disorder. The existence of the unidirectional charge-density wave state at
temperature $T<T_c$, where $T_c$ is the transition temperature, leads to the
anisotropic conductivity tensor. We find that the leading anisotropic
corrections are proportional to $(T_c-T)/T_c$ just below the transition in
accordance with the experimental findings. Above $T_c$ the correlations
corresponding to the unidirectional charge-density wave state below $T_c$
result in the corrections to the conductivity proportional to
$\sqrt{T_c/(T-T_c)}$.
