Twin Transit Paratransit Service
As a requirement of the Americans with Disabilities Act of 1990, Twin Transit offers ADA Complementary Paratransit service to passengers who are prevented from using the fixed route bus system due to a functional or cognitive mobility limitation.  ADA Paratransit is a reservation based door-to-door service that serves any location within 3/4 of a mile of a Twin Transit fixed route.  

Applying for ADA Paratransit
Passengers interested in ADA Paratransit service must submit an application for approval.  Relative to the fixed route, ADA Paratransit is a very expensive public transportation service and Twin Transit has the responsibility to ensure that the service is limited to only those passengers who are genuinely prevented from using the fixed route system.  Paratransit eligibility may be denied to applicants seeking paratransit approval for purposes of convenience or discomfort.

The application process involves collecting mobility information from a doctor or other professional health care provider who can describe how the passenger's limitations prevent access and use of the fixed route bus system.  Professional documentation affirming a passenger's limited mobility is a requirement of a completed application.  Additionally, an in-person interview may be conducted between the passenger and Twin Transit staff to discuss the passenger's mobility and the specific barriers preventing reasonable access and use of the fixed route system.  Approved passengers are issued an ID card and are eligible to reserve trips on Paratransit vehicles through the Twin Transit dispatch office.  All approved Paratransit passengers are encouraged to use the fixed route system whenever possible.

Scheduling a Ride
Approved Paratransit passengers may schedule trips by contacting Twin Transit dispatch at (360) 330-5555.  Reservation hours are Monday - Friday between the hours of 8:00 am and 4:00 pm.  When calling to make a trip request, please have ready your:

  • Name
  • Date and Time of pickup
  • Address of pickup
  • Address of destination
  • Number of travel companions or accompanying Personal Care Attendant (PCA)

Paratransit is a reservation based system as well as a shared ride system.  This means that passengers may be on the bus with other passengers traveling to other destinations.  Passengers traveling on ADA Paratransit vehicles can expect some trips to require a comparable amount of time as would be required on the Twin Transit fixed route system.

Note:  Twin Transit uses a combination of paratransit reservations and fixed-route deviations to meet eligible demand
