The two-lane roads (Bundesstrassen) along the coast can be full of traffic in summer. The ones leading to Usedom Island can be extremely log-jammed, as the causeway bridges have scheduled closings to let ships pass. Using the Bundesstrassen takes more time, but these often tree-lined roads are by far more scenic than the autobahn.
Sylt island is 196 km (122 miles) from Hamburg via autobahn A-7 and bundesstrasse B-199 and is ultimately reached via train. B-199 cuts through some nice countryside, and instead of A-7 or B-76 between Schleswig and Kiel you could take the slow route through the coastal hinterland (B-199, B-203, or B-503). Lübeck, the gateway to Mecklenburg-Vorpommern, is 56 km (35 miles) from Hamburg via A-1. B-105 leads to all sightseeing spots in Mecklenburg-Vorpommern. A faster route is the A-20, connecting Lübeck and Rostock. From Stralsund, B-96 cuts straight across Rügen Island, a distance of 51 km (32 miles). From Berlin, take A-11 and head toward Prenzlau for B-109 all the way to Usedom Island, a distance of 162 km (100 miles). A causeway connects the mainland town of Anklam to the town of Peenemünde, on Usedom Island; coming from the west, use the causeway at Wolgast.
