 After the MRT-7 proposal was awarded, the plans were revived to create a separate line for the remainder of the alignment from the original MRT-4 proposal that the MRT-7 left out which was named MRT-9 that was envisioned to traverse from Lerma to North Avenue.Subsequently this was again shelved in favor of a BRT line that traverses from Lerma to UP Diliman but was again shelved now in favor of an unsolicited proposal put up by PNR and Alloy MTD using the same remaining MRT-4 and BRT alignment with the working project name "PNR East-West Rail" and is believed to be officially numbered Line 8, should the proposal push through.The boulevard will also provide access to the northern extension of Metro Manila Skyway via España Exit.
