New Streetcar System Opens In Tucson
A new streetcar system will start running Thursday in Tucson.
Construction began in 2012 on the $200 million project. The Sun Link streetcar line connects the University of Arizona with the downtown area. Each of the eight streetcars can carry about 150 people.
Rides on the nearly 4-mile line will be free for the first three days. Then it will cost $1.50 to ride one way or $4 for an all-day pass.
