TUCSON - A new streetcar system in Tucson is officially on track.
U.S. Department of Transportation officials and Tucson Mayor Jonathan Rothschild were among those on hand Friday morning at the grand opening of the nearly 4-mile Sun Link streetcar.
Eight streetcars, which can each hold about 150 people, will cover the 18-stop route.
The line connects the University of Arizona, the University of Arizona Medical Center and the downtown area.
Construction on the nearly $200 million project began in 2012.
Federal transportation officials say the streetcar line will spur economic development and improve transit options for thousands of residents.
Streetcar rides will be free Friday through Sunday.
Regular fares are $1.50 for a one-way ride, $4 for an all-day pass and $42 for a 30-day pass.
