^^ Well even if no dualling of the road on the UA side happens anytime soon, that need not be an obstacle for M3 being opened all the way to the border. The two lanes may be merged into one just before the crossing - or at some distance from it, designing one of the lanes as truck waiting corridor.
On the westbound side, no issues at all, the two-lane carriageway may start right from the border station.
