Most of Sacramento's downtown streets are one-way, with a synchronized traffic light system. The major thoroughfares are the freeways: Interstate 80 and Business 80, which run from the west to the northeast, and Interstate 5, which runs north and south. Other important roads are the Garden Highway, running east and west, and State Highway 99, coming from the southern part of the city to join Business 80. In downtown Sacramento, the streets running east and west are named by letter; streets running north and south are designated by number.
Sacramento Regional Transit Company (RT) operates more than 250 buses on 80 area bus routes. The RT also owns the electrically powered light rail system, which consists of 76 light rail vehicles traversing 30 miles of light rail, connecting the suburbs with downtown. The bus and rail systems are accessible to the disabled community. In 2002, the systems served 27 million passengers.
