Sacramento (SMF) on SacRT route 142 and the Yolobus 42s

Route 142 runs express to downtown Sacramento every 20 to 30 minutes, seven days a week, combined with Yolobus 42A and 42B.

  • SacRT route 142 is the airport express bus, running to downtown Sacramento.
  • Every 20 to 30 minutes, seven days a week.
  • It works in combination with Yolobus routes 42A and 42B, which serve the airport from the Yolo County side.
  • Yolobus reaches Davis and Woodland as well as Sacramento, which is the useful part if you are heading for UC Davis.
  • A SacRT single ride ticket is 2.50 dollars.
  • A daily pass is 7.00 dollars, semi-monthly 50.00, monthly 100.00.
  • A transfer ticket is 25 cents.
  • Seniors 62 and over, riders with disabilities and students TK to 12 pay 1.25 a single ride and 3.50 for a day.
  • Many students in grades TK to 12 ride free under the RydeFreeRT scheme.

The express bus

  • SacRT route 142 runs an express service between Sacramento International Airport and downtown Sacramento.
  • Every 20 to 30 minutes, seven days a week, in combination with Yolobus routes 42A and 42B.
  • That combination is the point. The airport sits north-west of the city near the Yolo county line, and two agencies split the work.

Yolobus, and why it matters

  • Yolobus runs daily routes across the region, from Sacramento to Davis and Woodland and beyond.
  • If you are heading for UC Davis, that is the direct answer rather than going into Sacramento first.
  • The 42A and 42B are a loop - one runs clockwise and one anticlockwise around the same circuit through the airport, Woodland, Davis and downtown Sacramento.

SacRT fares

  • Single ride ticket 2.50 dollars. Transfer ticket 25 cents.
  • Daily pass 7.00 dollars. Semi-monthly 50.00, monthly 100.00.
  • Discount fares are half: 1.25 a single ride, 3.50 a day, for seniors 62 and over, riders with disabilities and students from TK to grade 12.
  • A Super Senior monthly pass for over-75s is 40.00 dollars.
  • Many school students ride free through RydeFreeRT - worth checking with the district if you are local.

Landing here

  • The airport is about 16 km north-west of downtown Sacramento, on the flat delta land beside Interstate 5.
  • This is the airport for the state capital and for Lake Tahoe, which is a two-hour drive east and not served by any bus from here.
  • San Francisco is 145 km south-west. SMF sometimes prices well against the Bay Area airports, and the drive is real but manageable.
