Exciting news! Did you know that Twin Transit is launching weekday service from Centralia to Castle Rock? The Purple line will start service on August 15, 2022, running Monday – Friday from 6 am – 7 pm. Twin Transit passengers can connect with Lower Columbia CAP transportation, RiverCities Transit and Cowlitz Tribal transportation and ride all the way to Kelso, Longview, Vancouver, and beyond! 

  • Now you can commute to work in Winlock, Castle Rock, Kelso and Longview.  
  • You can head to Castle Rock to connect to Longview where you can explore numerous recreation parks.

We’ve heard your feedback and are pleased to offer this new route for an even better, more streamlined transit system. Twin Transit will pilot the Purple line through March of 2023, when we will use ridership data and rider feedback to make any necessary adjustments to this route.
