North Sea The nearest passenger ferries to Hook of Holland actually depart from Harwich, across the Orwell south of Felixstowe. That ferry has 2 daily departures, one is a day crossing, the other a night crossing, both taking about 7–8 hours. It carries foot (train) passengers and cyclists as well as cars, buses, caravans and freight lorries. The ferry has bunks and rooms available to accommodate those on either crossing. Tickets for Dutch rail travel can be purchased on the ship. Ferries departing from Felixstowe carry freight only.

 Kazakhstan/ Russia Border crossingThe Russian stretch of this road coincides partly with the Asian Highway Network's AH6 (though this latter highway passes through Petropavl, Kazakhstan in its stretch between Chelyabinsk and Omsk, unlike the E 30). The E 30 follows the Russian main road M1 Belarus-Moscow, M5 Moscow-Chelyabinsk, and R254 Chelyabinsk-Kurgan. It goes along minor roads past Ishim to avoid the Kazakh border towards Omsk.
