E5 expressway (Philippines)

NLEX Segment 8.1 (Mindanao Avenue Link) westbound towards Smart Connect Interchange

NLEX Segment 8.1 (Mindanao Avenue Link) is a four-lane, 2.7-kilometer (1.7 mi) expressway that runs from the Smart Connect Interchange to Mindanao Avenue in Valenzuela. Lying on the ground level east of the interchange, it begins at the intersection with Mindanao Avenue in Barangay Ugong and then approaches the Mindanao toll plazas, widening to 6 lanes serving only westbound traffics. It terminates at the Smart Connect Interchange with NLEX Main and continues to the west as Segment 9 (Karuhatan Link).

NLEX Segment 9 (Karuhatan Link) westbound

NLEX Segment 9 (Karuhatan Link) is a four-lane, 2.4-kilometer (1.5 mi) expressway that runs from Smart Connect Interchange to MacArthur Highway in Karuhatan, Valenzuela. It is the first segment of the NLEX Harbor Link project.[14] It begins at the Smart Connect Interchange with NLEX Main, picking-up from where Segment 8.1 (Mindanao Avenue Link) left off. Lying on the ground level west of the interchange, it then traverses Barangays Gen. T. De Leon, Parada, and Maysan, where two exits towards the first two barangays, respectively, are found. It then enters Barangay Karuhatan, where it approaches the Karuhatan toll plaza, widening to 6 lanes serving only eastbound vehicles, and Segment 10 (Harbor Link) and finally terminates at MacArthur Highway.

The C3–R10 section westbound

NLEX Segment 10 (Harbor Link), the second phase of the NLEX Harbor Link project, is a four-lane, 5.65-kilometer (3.51 mi) fully elevated expressway which connects with the Karuhatan Link (Segment 9) in Valenzuela to C-3 Road in Caloocan, where two ramps carry it to the west for another 2.6 kilometers (1.6 mi) up to Radial Road 10 (R-10) in Navotas.[14] It begins at Karuhatan Exit with Segment 9 (Karuhatan Link) and MacArthur Highway. The section near the northern terminus traverses an industrial and residential area, which necessitated the demolition of numerous houses, buildings, and warehouses. It soon follows the railway right-of-way where it rises up to as high as 19 meters (62 ft) to provide necessary ground clearance for the viaduct carrying the future Manila–Clark Railway of the Philippine National Railways (PNR). It then crosses Tullahan River, where it enters Malabon. It then enters Caloocan, where past Samson Road and the PNR rolling stock shops in Caloocan, it shifts east of the railway's right of way, which also necessitated the demolition of a wet market. An exit to C-3 Road could then be found before meeting the Caloocan Interchange, where the expressway veers west as the C3–R10 spur alignment with connection to the under-construction NLEX Connector (NLEX-SLEX Connector Road) that would lead southwards to Manila. The 2.6-kilometer (1.6 mi) C3–R10 section runs above C-3 Road, where a westbound exit ramp towards Dagat-Dagatan Avenue could be found. It then crosses the Navotas River and enters Navotas, where it veers southeast towards R-10 and ends at the Navotas Interchange, which provides access to the Port of Manila via Mel Lopez Boulevard.

At the Navotas Interchange, the expressway has a possible future connection to the proposed NLEX–CAVITEX Port Expressway Link or Harbor Link Port Access Mobility Facility towards Manila–Cavite Expressway (CAVITEX) or Anda Circle, respectively.[15][16]

NLEX Segment 8.2, also named NLEX C-5 Link and NLEX Citi Link,[14][17] will be an 11.5-kilometer (7.1 mi) segment part of the NLEX Harbor Link Project that will connect the existing NLEX Segment 8.1 (Mindanao Avenue Link) to Katipunan Avenue, a part of C-5. It is divided into two sections: the 8.30-kilometer (5.16 mi) Section 1 from Mindanao Avenue to Luzon Avenue and the 3.2-kilometer (2.0 mi) Section 2 from Luzon Avenue to C.P. Garcia Avenue.[2][18][19] The planned segment will at first run parallel to Republic Avenue before making a southward turn to Luzon Avenue after which it will then cross to Commonwealth Avenue and end at the intersection of C.P. Garcia and Katipunan Avenues.[14] The segment will include five interchanges at Mindanao Avenue, Quirino Highway, Regalado Avenue, Congressional and Luzon Avenues, and Katipunan and C.P. Garcia Avenues, with three local road crossings at Sauyo Road, Chestnut Avenue, and Commonwealth Avenue.[20][21]

The project implementation has been delayed for years due to right of way issues,[22][23] as it will affect informal settlers in 8 barangays of Quezon City.[24] Construction of the expressway segment's 2-kilometer (1.2 mi) Section 1A between Mindanao Avenue and Quirino Highway is set to commence in September 2021.[25]
