The Autopista Urbana Conexión Oriente is an A4 toll road of approximately 6.8 km, designed to improve connectivity between the Anillo Periférico Oriente, the Calzada Ignacio Zaragoza and the Peñón-Texcoco highway, on the borders of the State of Mexico and Mexico City.
The project includes two operational sections: section A, from Autopista Peñón-Texcoco to Av. Bordo de Xochiaca (3.3 km), with 1.1 km of elevated viaduct and 1.6 km at grade; and section B, from Av. Bordo de Xochiaca to Calzada Ignacio Zaragoza (3.5 km), almost all on elevated viaduct.
