Circumferential Road 3
Circumferential Road 3, informally known as the C-3 Road, is a network of roads and bridges which comprise the third beltway of Metro Manila in the Philippines. Spanning some, it connects the cities of Caloocan, Navotas, Quezon City, and San Juan.
The road's segment from its northern terminus at Radial Road 10 in Navotas to its intersection with Magsaysay Boulevard and Aurora Boulevard in Quezon City forms the entire National Route 130 of the Philippine highway network
History
The development of a major road network in Manila was first conceived in the Metropolitan Thoroughfare Plan of 1945, predicting that the metropolis would expand further to the shorelines of Laguna de Bay. The plan proposed the laying of circumferential roads 1 to 6 and radial roads 1 to 10.The route was originally planned to be a complete beltway around the city of Manila, from Navotas in the north to Pasay at the south. In 1978, the feasibility study conducted by the Japan International Cooperation Agency of the road was conducted, consisting of two projects: the main route between Ayala Avenue, Makati, and Rizal Avenue, Caloocan, and a spur leading to Balintawak, with a total length of. However, possibly due to right of way issues, the part between San Juan and Makati was not completed. The Metro Manila Skybridge was supposed to be the missing link of the route between G. Araneta Avenue in Quezon City and South Avenue in Makati, with several interchanges. However, it was cancelled due to the Skyway Stage 3 project occupying the portion of the San Juan River. South Avenue, Ayala Avenue Extension, and Gil Puyat Avenue were later removed from the alignment of C-3.
In the JICA-conducted study, the elevated Expressway Route C-3, was also planned as early as 1993 to traverse above the C-3 alignment from Navotas to Mandaluyong. Also, another proposal in the late 1990s, called the R-10/C-3 Expressway, totaling the length of from the Metro Manila Skyway to the Manila North Harbor, with a solicited proposal submitted by the joint venture of the Philippine National Construction Corporation and Kværner of Norway. The completion of this project will allow cargo traffic to pass without being hampered by urban congestion. In 2003, JICA also conducted a study again on the elevated expressway under a planned public-private partnership, with a length of , and in 2007, there are plans to extend the Metro Manila Skyway towards the port area as a linkage, but was only realized by the C-3–R-10 spur of NLEX Harbor Link and Skyway Stage 3 constructed and opened more than two decades later.
