 The original alignment would consist of Zamora flyover, crossing the Pasig River, meeting up with the NLEX-SLEX Connector near the PUP campus, and passing through Old Santa Mesa Road and V. Mapa Street.However, due to right-of-way issues, the alignment was forced to be realigned, veering right from Tomas Claudio Street through the San Miguel Yamamura Packaging Corporation plastic plant in Pandacan, and follow the San Juan River up to Gregorio Araneta Avenue.A second modification of the plans added a fifth segment at the north end of the project.
