  Using time-dependent Ginzburg-Landau theory we find oscillations of critical
current density $j_c$ as a function of the length $L$ of the bridge formed from
two-band superconductor. We explain this effect by appearance of the phase
solitons in the bridge at $j<j_c$, those number changes with change of $L$. In
case of sufficiently strong interband coupling oscillations of $j_c$ disappear.
