The route of the new Milan Eastern Outer Ring Road (TEEM) stretches for approximately 40 km, from Melegnano (junction with the A1 Milan–Bologna) to Agrate (junction with the A4 Milan–Venice). The infrastructure was designed to relieve traffic on the existing eastern ring road and on the Cerca provincial road (Melegnano, Melzo, Gorgonzola, and Agrate), as well as on the connected local road network.

Once completed, the TEEM will be an essential project for alleviating traffic congestion in the eastern quadrant of Milan, one of the busiest areas in Europe. The infrastructure spans 32 km, with three lanes plus an emergency lane in each direction, three interchanges with other highways, six junctions and toll plazas, 1.2 km of man-made tunnels, 7.3 km of cuttings, and 1.9 km of viaducts.
