We show that the dependence $\\delta F_{thr}(I)\\propto I_{dep}\\hbar(1-I/I_{dep})^{5/4}/e$, found by Langer and Ambegaokar for a long bridge with length $L \\gg \\xi$, holds far below the critical temperature both in dirty and clean limits (here $I_{dep}$ is the depairing current of the bridge and $\\xi$ is a coherence length).
