Currently, there is no mass rapid transport system (MRTS) linking the two airports, and the Metro 8 corridor, part of the Mumbai Metropolitan Region Development Authority (MMRDA) Metro Master Plan, is designed to address this gap.

Ahead of the assembly elections, discussions were held to finalize which agency would take charge of the project, as the route spans both Mumbai and Navi Mumbai. While the MMRDA and the state government supported the idea of the City and Industrial Development Corporation (Cidco) executing the project through Maharashtra Metro Rail Corporation (Maha Metro), the then Chief Minister Eknath Shinde preferred that the MMRDA oversee the 35-km corridor.

A state government official mentioned, "The then chief secretary and MMRDA were inclined towards Cidco executing the project through Maha Metro, as the majority of the route falls within Navi Mumbai." However, Shinde could not reach a final decision. Now, with the Navi Mumbai airport set to open next year, the new government under Chief Minister Devendra Fadnavis is expected to expedite the Metro 8 project.
