Flatiron Flyer.
The new bus line promises faster travel by using the express toll lane that opened on U.S. 36 in July.
The Flatiron service will consist of six routes – some previous routes were dropped to decrease travel times. One-way fares will range from about $2.50 to $4.50. Riders have two options – express service with few stops between Denver and Boulder – and the all-station service.
