    Making reservations for the Express Routes is encouraged the day prior to secure a space as capacity will be limited.

  • Monday, October 5th, 2020 - Route 6 North Mesa re-opening:

    Atomic City Transit is pleased to announce re-opening of fixed- Route 6 – North Mesa in Los Alamos County beginning Monday, October 5th. Route 6 will join the current bus service of Routes 1, 2M, and 2T that began on June 15th with reduced service hours from approximately 7:30 AM to 5:30 PM - Monday through Friday. See our Routes & Schedules page for details.

  • Monday August 3, 2020 TEMPORARY DETOUR Rts 1 & 2M:

 Due to road construction on Central Ave, routes 1 & 2M inbound towards the Transit Center will detour onto Trinity Dr at Central Ave, make a right onto Knecht St, and left back onto Central Ave. Bus stops at Central Ave & 4th St, 6th St, and 9th St will be closed during this period.

  • Monday, June 15th, 2020 - Phase One of Fixed-Route re-opening:

Atomic City Transit is pleased to announce plans for the phased re-opening of fixed-route public transportation in Los Alamos County beginning Monday, June 15th. Phase-one of reopening fixed-route bus service will include Routes 1, 2M, and 2T operating on reduced hours of daily service, from approximately 7:30 AM to 5:30 PM - Monday through Friday.

A critical factor, as we begin this initial phase of resuming bus service, is maintaining passenger safety by complying with public health recommendations. In accordance with the current Governor’s Executive Order:

  • Passengers will be required to wear face coverings in order to board and ride the bus
  • The number of passengers allowed on each bus will be limited to comply with social distancing recommendations
  • Some seats on every bus will be blocked-off to assure adequate spacing between passengers again to comply with social distancing recommendations

Atomic City Transit staff have also implemented the following measures to further enhance public health safety as we begin to resume fixed-route bus service:

  • Hand sanitizer will be available on all vehicles for both customers and staff
  • All transit vehicles will be thoroughly cleaned and disinfected prior to being put into daily service, as well as high touch areas disinfected between trips, throughout the day
  • Passengers will board and depart the bus only through the back doors only (when available)

Atomic City Operations and Dispatch staff will monitor bus capacity on the routes, and will dispatch additional buses on occasions if/when capacity limits are reached. However, in such situations, schedule delays will occur. Thank you in advance for your understanding as we address such issues during the re-opening

The Dial-A-Ride service, currently in operation County-wide, shall continue with the same service hours from 7:30 AM to 5:30 PM - Monday through Friday, for all areas of the County not serviced by Rt 1, 2M, or 2T. Dial-A-Ride service is available to any person and is curb to curb service with ADA accessible vehicles. Please call our office (505) 661-RIDE (7433) the day prior and schedule your appointment. You can also call the same day and book your trip on a space available basis.

For the specific Route 1, 2M, and 2T service schedules, that will go into operation on June 15th, please see the phase 1 section on our Routes & Schedules page, or use these links:


  • Effective Wednesday, March 18th: all fixed-route services are suspended until further notice in effort to reduce the impact of COVID-19. In the meantime, we will be providing Dial-a-Ride services between 7:30 AM and 5:30 PM, Monday – Friday. Reservations will be accepted up to 1 day in advance. Please call us at 661-RIDE (7433) if you would like to schedule a trip.
