The Herzegovinian municipality of Neum in the south makes the southernmost part of Croatia an exclave and the two countries are negotiating special transit rules through Neum to compensate for that. Recently Croatia has opted to build a bridge to the Pelješac peninsula to connect the Croatian mainland with the exclave but Bosnia and Herzegovina has protested that the bridge will close its access to international waters (although Croatian territory and territorial waters surround Bosnian-Herzegovinian territory and waters completely) and has suggested that the bridge must be higher than 55 meters for free passage of all types of ships. Negotiations are still being held.
