From your specific location within Victoria Island (e.g., around Ajose Adeogun, Eko Hotel Roundabout, or Landmark Beach), locate a yellow commercial bus (danfo) stop. Board a bus explicitly heading towards 'CMS' or 'Outer Marina'. These buses are frequent.

Inform the conductor you are dropping at 'CMS' or 'Under Bridge'. This is a major interchange. Alight at the designated bus stop, which is a bustling hub for various routes.

At CMS, navigate towards the main bus park located directly under the bridge. This area is a central point for buses heading to different parts of the mainland. Look for buses specifically marked 'Oshodi' or 'Mile 2 / Oshodi' that indicate they are taking the Third Mainland Bridge route.

Board the Oshodi-bound bus. It is crucial to confirm with the conductor that it is going directly to 'Oshodi Transport Interchange' or 'Oshodi Bus Stop' to avoid dropping at an earlier stop like Jibowu or Fadeyi if your destination is the main interchange.

The bus will drop you at the modern Oshodi Transport Interchange. Pay close attention as the conductor announces 'Oshodi' or the bus slows down at the Interchange to alight.

If your final destination in Oshodi is not the main interchange (e.g., Bolade, Mafoluku, Isolo, Arena Market), you might need to take a short local bus ride or a 'Keke Napep' (tricycle) from the Interchange's designated local connection points.
