$2.00 gets you from MSN to the Capitol on Route 20
Metro Transit Route 20 is the only city bus that pulls directly into the Dane County Regional (MSN) airport loop outside the Main terminal, and it runs to the Capitol area for $2.00 a ride. In light traffic, the in-vehicle time from the airport to downtown is usually 25–35 minutes, but you should plan on 35–45 minutes door to door once you add waiting. Pay cash on board or use a Metro pass; drivers don’t give change, so bring small bills.
Service is weekday-only with big gaps: Route 20 generally comes every 30–60 minutes during the day, with no late-night trips and no Sunday service at all. That “every 30–60” means you might luck into a bus within 10 minutes of landing, or you might sit at the curb outside baggage claim for nearly an hour. If your flight lands in the evening, assume the bus may already be done for the day and check the current schedule before you board your plane.
The sweet spot is East Washington Avenue hotels and near east side addresses, because Route 20 runs straight from the airport loop to East Wash without forcing you through a downtown transfer first. If your hotel is one of the chain properties along East Wash, you can often ride door to near-door for $2.00 instead of a $25+ Uber. Riders on r/madisonwi specifically call it “stupidly cheap” for that corridor when it’s running.
Here’s how to use it in 5 steps: 1) After exiting the Main terminal baggage claim, follow signs to the airport bus stop on the inner loop. 2) Check the posted Metro timetable or your phone to confirm the next Route 20 toward Capitol/East Washington. 3) Have $2.00 ready (as of 2024) or a valid pass before the bus arrives. 4) Tell the driver your stop, like “Capitol Square” or a specific East Washington cross street, and watch the interior display for your stop name. 5) Pull the yellow cord before your stop, exit, then walk the last block or two to your hotel or destination.
Regulars sometimes time flights to land while Route 20 still runs, then transfer downtown to another route for the UW campus or west side within the standard transfer window. Others mention that if Route 20 is off the clock, they’ll walk out to East Washington Avenue and use more frequent trunk routes from there, but only with light bags and decent weather. That walk is roughly 10–15 minutes depending on your pace.
Watch out for three things: the early evening cutoff, the total lack of Sunday service, and occasional confusion after network redesigns about whether Route 20 still hits certain East Wash stops. Before you rely on it, pull up the current Route 20 map on cityofmadison.com/metro and match your hotel’s exact address to a stop name. The practical move: have Uber, Lyft, or a local cab number saved in your phone as a backup in case your flight or the bus schedule slips.
