Traveling downtown and trying to park during the work week can be a hassle. However, the RTA is a great option to use especially when you work near tower city. The Ohio City Station is a part of the red line that leads directly into Tower City (downtown). Once you reach the station you can either purchase your ticket via the machine located before the stairs or purchase a ticket on the mobile app. For an unlimited daily pass it cost $5.50 for a regular person or $3.75 for students. Once you get your ticket you can head downstairs and hop on a train. Once you arrive at your station make sure to have your ticket or phone out. As you exit you will be required to swipe or scan your ticket.
Tip: I would recommend downloading the mobile app. The app allows you to plan routes, check the schedule, and purchase tickets. I have used it several times to figure out when to leave.
