Black branes are studied in Einstein-Gauss-Bonnet gravity. Evaporation drives black branes toward one of two singularities depending on the sign of {alpha}, the Gauss-Bonnet coupling. For positive {alpha} and sufficiently large ratio {radical}({alpha})/L, where L/2{pi} is the radius of compactification, black branes avoid the Gregory-Laflamme (GL) instability before reaching a critical state. No black branes with the radius of horizon smaller than the critical value can exist. Approaching the critical state branes have a nonzero Hawking temperature. For negative {alpha} all black branes encounter the GL instability. No black branes may exist outside of the interval of the critical values 0{<=}{beta}<3, where {beta}=1-8{alpha}/r{sub h}{sup 2} and r{sub h} is the radius of horizon of the black brane. The first order phase transition line of GL transitions ends in a second order phase transition point at {beta}=0.
