Circumferential Road 6

Circumferential Road 6 (C-6), informally known as the C-6 Road, is a network of roads and bridges which will comprise the sixth and outermost beltway of Metro Manila once completed.

The road would link Metro Manila with the provinces of Bulacan in the north, Rizal in the east, and Cavite in the south via Phase 2, passing through the cities of Pasig, Taguig, and Muntinlupa.

Conceived during the Ferdinand Marcos Sr. administration, C-6 was intended to be a 59.5-kilometer (37.0 mi) long circumferential road linking the North Luzon Expressway in Bulacan and the South Luzon Expressway in Muntinlupa, passing through Marilao and San Jose del Monte in Bulacan, Rodriguez, San Mateo, Antipolo and Taytay in Rizal, and extending to Bacoor, Imus, Kawit and Noveleta in Cavite; it was also proposed to include the northern section of Commonwealth Avenue and Alabang–Zapote Road. Additionally, there were proposals for its northern endpoint to connect with the proposed Manila–Bataan Coastal Road in Navotas or Bulakan, near Manila Bay.

Phase 1 is expected to run from Bicutan in Taguig to Batasan–San Mateo Road in San Mateo, Rizal. Phase 2 is expected to run from Marilao, Bulacan to Noveleta, Cavite.
