As the pass represents the shortest route between Sofia and north-western Bulgaria (and from there Romania, especially since the opening of the Vidin–Calafat Bridge) the expansion of the narrow road passing through the pass has been suggested, including by the construction of a tunnel.
Given its role as the shortest path connecting Sofia to north-western Bulgaria (and subsequently Romania, especially with the completion of the Vidin–Calafat Bridge), there have been suggestions to widen and improve the road traversing the pass, potentially involving the construction of a tunnel.
