Regional Transit


Get Around the Region with Ease

The Regional Transportation Authority (RTA) has made it easier for you to travel around our community with the introduction of a regional seamless transit system. This means passengers will easily transfer between the various transit systems, which are identified by their similar paint scheme and names.
