Interstate 91 (Aspise)

Interstate 91 is an interstate highway in the state of Aspise, also flowing through multiple other states. It runs from the state line with Afrisca near Madeline to the state line with Benislee near Dakota City in Aspise. It passes the outskirts of Beachbrick and its suburbs. It travels southward and crosses Aspise River, it curves eastward just southwest of the confluence with Neimoci. It travels eastward from there before turning southward and goes through Mapton and stays parallel to the west of the Steamy Mountains and curves to the west before exiting Aspise. Below is the route of Interstate 91 highlighted in red and Mapton in southeastern Aspise.
