The Smart Connect Interchange, also known as the Mindanao Avenue Interchange and the North Luzon Expressway–Circumferential Road 5 Interchange, is a two-level cloverleaf interchange in Valenzuela, Metro Manila, the Philippines which serves as the junction between Circumferential Road 5 (C-5) and the North Luzon Expressway (NLEx). Built as part of the 2.7-kilometer (1.7 mi) NLEx–Mindanao Avenue Link segment extending the expressway to Mindanao Avenue, which has since been incorporated into the C-5 system, it is the Philippines' largest cloverleaf interchange in terms of land area.
