Congressional Avenue (fil|Abenida Kongresyonal) is a 6km (04miles) six-lane highway in Quezon City, Philippines. It is one of the secondary roads in Metro Manila. Part of it is designated as part of Circumferential Road 5 (C-5) of the Manila arterial road system and National Route 129 (N129) of the Philippine highway system.
Congressional Avenue starts from the intersection between EDSA and FPJ Avenue (formerly Roosevelt), passes through some of the Project areas, Tandang Sora, Culiat, and Pasong Tamo, and ends at Luzon Avenue at the boundary of Matandang Balara.
The avenue is one of the rising food destinations in Quezon city because many food establishments, such as food parks, have set up shop along Congressional Avenue Extension.
Congressional Avenue follows an L route from EDSA to Luzon Avenue. The main segment, west of the intersection with Visayas Avenue, is characterized by numerous intersections. Major intersections are enforced with signal lights, while minor intersections are either unsignaled or use improvised U-turn slots. The extension segment, east of the intersection with Visayas Avenue, is characterized by partial access control, where at-grade intersections are replaced by U-turn slots. The outermost lanes along the entire stretch of the avenue are designated as bicycle lanes.
According to the 1949 Plan of Quezon City, Congressional Avenue was supposed to connect to the National Government Center at Constitution Hills (present-day Batasan Hills),[2] which would house government offices, including the Congress, from which its name is apparently derived. However, this plan was partially materialized as the road did not reach that area.
In the early 2010s, the avenue was envisioned to be extended into Luzon Avenue to complement the completion of the Circumferential Road 5, which includes the widening of the C.P. Garcia (through U.P. Campus) and Luzon Avenues, the Extension of Congressional Avenue, and the construction of the Luzon Avenue Flyover, which aims to divert C-5 and traffic from the narrow Tandang Sora Avenue in going to the Project areas and Mindanao Avenue towards the C-5 segment of North Luzon Expressway.
