We report the superconductivity in the single crystal of Sr2.5Ca11.5Cu24O41 at Tc(onset) = 6.5 K under an optimal pressure of about 4.5 GPa. Normal resistivity along ladder direction ρc, gradually changes from T-linear to T2-dependence with increasing an applied pressure. The normal resistivity ratio ρa/ρc in the ladder plane indicates the crossover from 1D to 2D with increasing an applied pressure.
