The 3.1-km corridor 7A will have an underground stretch of 2.1 km as there will also be twin tunnels and the contractor will be using the cut-and-cover method in which the stretch will be dug up and then reinstated after work is completed. The corridor will take the elevated route from Andheri east to Airport colony from where it will go underground up to the airport station of Metro 3. There will be two stations and the Airport Colonies will be elevated, while the Metro T2 station will be underground and it will be integrated with Metro 3 (Colaba-BandraSeepz) station. Work orders for Line 7A were issued along with those for Line 9 (Dahisar to Mira-Bhayander) last year.
