I want to know the answer to the following question:
Which freeway spans the large Bolte Bridge?
All the background I'm provided with is that "Like many Australian cities, Melbourne has a high dependency on the automobile for transport, particularly in the outer suburban areas where the largest number of cars are bought, with a total of 3.6 million private vehicles using 22,320 km (13,870 mi) of road, and one of the highest lengths of road per capita in the world.". Is that enough to answer the question?
Answer: no
