Can You Cross The Map Without Using Roads In GTA Vice City?

Is it possible to traverse the whole map of Grand Theft Auto: Vice City without touching roads? An interesting challenge initially proposed by ‪@monsieur_addax‬ in San Andreas, now attempted in GTA VC. While using ramps, bumps and rooftops, I try to reach my destination without using any road.
