Who's the official operator?

Operator is Central Contra Costa Transit Authority. This is the official company responsible for the route. If you run into problems (rude driver, breakdown, dirty vehicle, delays)—contact them. It helps to note the time, direction, and route number—makes your complaint more specific and gets handled faster. Contact info is usually on the company website or in transit apps.

Which transit system does it belong to?

This route is part of the 'County Connection' transit system. Within one network, payment and transfer rules are often consistent. Terms can differ though, so check current fares and payment methods in up-to-date sources before your trip.

How long from first stop to last?

Full journey takes about 00:45 in normal traffic. During rush hour or road work, it can take noticeably longer. If your trip is time-sensitive, add cushion and check arrival predictions on official sources.

What color is the route on maps?

On transit maps this route is marked in #1E6B9B. Color helps you spot the line quickly and tell it apart from others. In some cities the line color appears on stop signs or even on the vehicles themselves. The exact shade might vary between sources—go by route number and endpoints instead.

Is there a fare?

Yes. Payment rules and discounts can differ by region and vehicle type. If it matters to you, verify current fares and ticket/validation requirements before traveling.

What payment methods are available?

Payment methods: cash, Clipper. In practice, options can vary depending on how new the vehicle is and what equipment it has. Have a backup payment method just in case, and check the validator or ask the driver when boarding.

Can you board with a wheelchair?

Yes. Accessibility usually means low-floor entry with ramps and designated spaces. Even when accessibility is stated, conditions can vary on specific vehicles and stops. If this is critical, check the vehicle type for your specific trip and confirm ramp/entry availability beforehand.

Are bikes allowed?

Yes. If allowed, still try to avoid rush hour—in a packed vehicle with a bike it's rough for you and everyone else. Check the rules ahead: sometimes you need to fold the bike or buy a separate ticket.
