No.. You can't use it as of now. No connectivity. DHL is 5 kms up north from the Access road connection to NH 7. Which means it is 10 kms from the BIAL.
I was thinking on why they didn't construct one station near the BIAL. It passes right under the BIAL access road. Atleast people can make transfers for the rest of the 5 kms to reach BIAL.
