About HTA

The Humboldt Transit Authority

Humboldt Transit Authority (HTA) has served generations of riders since 1975, connecting communities across Humboldt’s distinctive scenic landscape and beyond. Formed as a Joint Powers Authority (JPA) by Humboldt County and the cities of Trinidad, Arcata, Eureka, Fortuna, and Rio Dell. HTA is headquartered in Eureka. Our local and regional transit services all fall under one name, Ride Humboldt. It encompasses the Redwood Transit System (RTS), Southern Humboldt Intercity (SHI), Arcata & Mad River Transit (AMRTS), North State Express 101 (NSE 101), and North State Express 299 (NSE 299), alongside Ride Humboldt Flex and paratransit. By bringing these services together, we’re making it easier to travel around Humboldt and connect with destinations beyond the county lines. Local leadership guides HTA through a seven-member Board of Directors, with one representative from each member city and two from Humboldt County. HTA’s stable funding comes primarily from passenger fares and Transportation Development Act (TDA) funds contributed by its member agencies. In addition to this, HTA is proactive in seeking competitive grants to balance its budget.

Our Routes and Fares

Ride Humboldt connects communities throughout Humboldt County and beyond for just $2 per ride on fixed route service, reaching as far south as Ukiah and as far east as Redding. Period passes, electronic tickets, and tap-to-pay options make traveling across our fixed-route network even easier. When riders use the same contactless payment method (credit, debit, or digital wallet), automatic fare caps limit what they pay to the applicable daily, weekly, and monthly pass rates.

More Ways to Ride


Your plans don’t always follow a fixed route schedule, so our services extend beyond our traditional fixed-route bus services. Ride Humboldt Flex offers on-demand trips between fixed route bus stops and “virtual” bus stops, with booking through the Ride Humboldt app or by phone.


Paratransit provides scheduled, shared rides for eligible riders with accessible transportation, helping more people travel with ease and confidence.

Investing in Our Humboldt Community

Humboldt Transit Authority is proud to directly employ its workforce, rather than using contract labor like many transit agencies. This includes all administrative, operational and maintenance staff. HTA trains its drivers in-house, with little to no prior experience required. This creates quality jobs with excellent benefits for our local workforce.


Big things are taking shape for Humboldt Transit Authority. HTA is investing in hydrogen-powered buses and fueling infrastructure to support cleaner travel and protect the forests and coastline that make Humboldt County so great.


In Old Town Eureka, the Eureka Regional Transit and Housing (EaRTH) Center will bring a new transit hub to our largest city, meeting regional mobility and affordable housing in one central location. Restrooms, bike lockers, and sheltered waiting areas will give riders a welcoming place to pause before their next connection. Ground floor commercial spaces will bring local businesses into the heart of the hub, offering more for riders and the wider community between trips, while affordable housing above will put regional transit connections right downstairs. It’s a step toward a more connected Humboldt, with public transit at the heart of a growing downtown.


Alongside local governments, schools, and community partners, HTA continues working to make public transportation more accessible and connected, helping people reach the places they need to go.
