Yes Call the TRA or just take an Uber its very easy as cleveland is not a busy airport anymore
You can use a back road or shuttles
Im not from Cleveland but my friends that picked me up from the airport are, and she doesn't like to go on the highway so so we stayed on the streets that we could use that weren't the highway.. so for the most part we did stay off of the Highway... I'm sorry that I couldn't tell you at all what streets those were because like I said Im not from there.. try putting the address in the GPS and I'm sure to give you more than one route to take...
RTA runs trains from the airport but you would have to check their website for schedules. Also, there are several shuttles that allow you to park elsewhere and ride the shuttle to the airport.
