On the Azerbaijani side, the Zangazur corridor was planned on 3 main pillars. The first is the air corridor. After Fuzuli Airport, the construction of the second airport in the region, Zengilan Airport, has now been completed. Warehouses and logistics centers will be located around the airports. As dear
@Bogeyman shared above, both airports are connected by an international standard highway and this line will reach Nakhchivan from the Zangazur corridor, then to the Turkiye border. The third pillar is the completion of the railroad connections.
(And the Zangazur corridor is actually a part and a stage of the trans-Caspian vision in a broader context. Full transportation integration of Central Asia and the Anatolian peninsula.)
In fact, the revival of the railway line was perhaps one of the most important issues in the Russian-brokered negotiations after the Karabakh victory. And Russia itself brought the Russia-Armenia and Russia-Azerbaijan-Turkiye railroad directly to the negotiating table. Weeks after the agreement, the Russian newspaper Kommersant published a map of the transportation routes, including the railway, agreed between Russia, Armenia and Azerbaijan in the capital Moscow. The map clearly showed a connection between Azerbaijan and Turkiye via Nakhchivan. The new project also includes a connection between Armenia and Russia. Thus, the railways, which were closed after the collapse of the USSR, will be revived after almost 30 years. The railway is a win-win opening that serves both Russian interests and Turkish-Azerbaijani interests, and was indeed one of the critical issues that brought the parties to the point of agreement. In fact, most of these issues are now beyond Armenia's reach and there is little it can do except drag its feet.
