TheSoutheast Metro Manila Expressway (SEMME), also known asSkyway Stage 4,C-6 Expressway and formerlyMetro Manila Expressway, is a proposed[5][6] 32.664-kilometer (20.296 mi)[2] tolled expressway running across easternMetro Manila and westernRizal. The expressway will help decongest the existing roadways across Metro Manila, such asEDSA andCircumferential Road 5. The expressway is part of the largerCircumferential Road 6 project, expanding from the original C-6 currently passing from General Santos Avenue in Taguig up to Highway 2000 (Phase 1) in Taytay, will expand to Cainta, Pasig, Marikina, San Mateo, and in Quezon City. Just like theC-5 Southlink Expressway andNLEX Harbor Link, Class 3 Trucks are allowed on this expressway
The expressway will begin at theSkyway nearFTI (nowArca South),Taguig with connections feeding from theC-5 Southlink Expressway, and end at theBatasang Pambansa Complex inQuezon City with a possible extension connection toNLEX Segment 8.2 at the Regalado Stack Interchange. It will also connect to theNorth Luzon Expressway (NLEX) inBalagtas,Bulacan via a northern spur diverting from the mainline Southeast Metro Manila Expressway.[7]
The entire expressway will be a future component ofExpressway 5 (E5) of thePhilippine expressway network.
In 1945, the Metropolitan Thoroughfare Plan was submitted byQuezon City planners Louis Croft and Antonio Kayanan, which proposed the laying of 10 radial roads to convey traffic in and out of the city ofManila to the surrounding cities and provinces and the completion of six circumferential roads that will act asbeltways of the city, forming altogether a web-likearterial road system, including the sixth circumferential road, which runs fromMeycauayan toLas Pinas. In 1973, it was proposed in the Urban Transportation Study in Manila Metropolitan Area (UTSMMA) that a highway be constructed betweenNavotas and Las Pinas.[8]
In 1983, under the administration of PresidentFerdinand Marcos, it was proposed that the highway would be atolled expressway known as the Metro Manila Expressway (MME), and the route would begin at theNorth Luzon Expressway in Meycauayan and end at theSouth Luzon Expressway in Bicutan,Paranaque. The total length is approximately 44.570 km. The plan was undertaken by thePhilippine National Construction Corporation (PNCC).[9] The proposal was revived in 1993 when PNCC signed an agreement to build the expressway with the Indonesian PT Citra Lamtoro Gung Persada (CITRA).[10]
The agreement was supplemented on February 14, 1994, with a related undertaking by CITRA. CITRA was to provide a preliminary feasibility study on theMetro Manila Skyways (MMS) project, a system of elevated roadway networks passing through the heart of the Metropolitan Manila area. To accelerate the actual implementation of both the MME and the MMS projects, PNCC and CITRA entered into a second agreement. Through that agreement, CITRA committed to finance and undertake the preparation, updating, and revalidation of previous studies on the construction, operation, and maintenance of the projects.[11] According to the CITRA proposal, the planned alignment was to have 38.4 kilometers from Meycauayan to Bicutan, the same route as the 1983 plan, while the remaining segments leading toSan Pedro were 18 kilometers and 19 kilometers toCavite.[12]
In the late 2000s proposal, the Circumferential Road involves a 59.5-kilometer tollway that links the North and South Luzon Expressways via the towns of Rizal and the eastern parts of Metro Manila. This tollway will traverse the cities ofSan Jose del Monte in Bulacan,Antipolo inRizal, andMarikina, Taguig, andMuntinlupa in Metro Manila. It shall also pass through the towns ofRodriguez/Montalban,San Mateo,Taytay, andAngono in Rizal andBacoor,Imus,Kawit, andNoveleta in Cavite.[13] The C-6 project was also included in the 2010Japan International Cooperation Agency (JICA) study on the High Standard Highway master plan,[14] the feasibility studies undertaken by theMinistry of Economy, Trade, and Industry, theJapan External Trade Organization and theKorean International Cooperation Agency with a full-scale FS.[15]
The plan was launched again in 2014 by Citra, PNCC, andSan Miguel Corporation. The Metro Manila Expressway, or C-6 Project, is actually Stage 4 of the South Metro Manila Skyway (SMMS). This toll road will stretch from Bicutan to San Jose Del Monte and will then connect to the proposedMRT-7 Project, which will extend to the NLEX. The toll road will have a length of 34.33 km, 7.62 km of which is the elevated portion, six (6) lanes with six (6) interchanges and 20 ramps, and a close toll collection system. The construction cost is estimated at P19.76 billion out of the total P29.84 billion project cost. The Restated Supplement to the Business and Joint Venture Agreement (Restated Supplement to BJVA) for the MME Project, executed in January 2014, contains the agreement of the parties and embodies the terms and conditions for MME.[16]
The project's groundbreaking ceremony was held on January 8, 2018.[7] The project was scheduled to be completed in 2022, but construction was delayed due toright of way issues for the Taguig segment. In November 2023,Ayala Land signed an agreement with SMC Infrastructure for an integration agreement to linkArca South to the Skyway, and in February 2025, the Department of Transportation signed with the private stakeholders for the Right of Way Usage Agreement.[17][18]
Exits will be numbered by kilometer posts, withRizal Park inManila designated askilometer zero.
