The vast majority of visitors to Davenport arrive via Interstate 80. Many also arrive using Intestate 74 through Bettendorf (the easiest route if arriving at the Moline International airport). The west end of Davenport can also be accessed from the I-280 bypass.
Most people commute through Davenport by car, but there is a very reliable city bus service.  While a few cab companies operate in Davenport and surrounding communities, visitors from larger metropolitan cities should not expect the cars to be waiting outside hotels or other places. It is advisable to place a call to a cab company at least 30 minutes prior to when you want to be picked up. Uber and Lyft are also both available.
