The city is an important hub of Brittany's motorway network and is surrounded by a ring road: the Rocade (national road 136). The construction of the bypass was started in 1968 and completed in 1999. It is 31 km (18.5 mi) long, it has 2 lanes each way (sometimes 3 lanes) and toll free. Many other expressways are connected to the Rennes ring road for local and regional service. By road, Saint-Malo can be reached in 45 minutes, Nantes in 1 hour, Brest in 2 hours and 30 minutes, Paris in 4 hours, Bordeaux in 5 hours, and Brussels in 6 hours and 30 minutes.
