The new Milan External East Bypass motorway directly connects A4 Torino-Trieste motorway at the Agate Briana junction to A1 Milan-Bologna motorway, with a total road length of 32 kilometers.
With a three lanes plus emergency lane per carriageway, the motorway is interconnected with the existing motorway network (A1 Milan-Bologna, BreBeMi and A4 Turin-Trieste) and with the ordinary roads system of the area, with junctions in Pessano and Bornago, Gessate, Pozzuolo, Liscate, Paullo and Vizzolo Predabissi.
TEEM runs for a total of 8.7 kilometers below the ground surface, while in the remainder of the route, the road is at ground level or on embankment. 2.1 km of viaducts have been built to overpass of waterways or rail lines, and one kilometer of artificial tunnels to cross areas with particular urban complexity.
In addition to the motorway, the TEEM Final design includes 19 major interventions on the secondary roads network: 38 kilometers of new roads and the rehabilitation works of 15 km of existing roads have been designed. 21 km of new cycle routes and requalification of 10 km of existing cyclist pedestrian have been implemented.
The new infrastructure has been divided in three separate lots: Lot A, in the north, with a length of 6.2 kilometers between the towns of Agrate Brianza and Bellinzago Lombardo; Lot B, the central section, with an extension of 15.8 km between the towns of Gorgonzola and Paullo; Lot C to the south, with a length of 9.9 km between the municipalities and Tribiano Cerro al Lambro. The project implementation activities include the so-called “Arco TEEM ‘motorway between SP 103” Cassanese “and SP 14” Rivoltana “, though which BreBeMi connects to the motorway and ordinary roads network of Great Milano.
