The TEEM route shall be interconnected with the existing and planned motorways (A1 Milan-Bologna, Bre.Be.Mi. and A4 Turin-Trieste) and also with the ordinary road network in the area (through junctions in Pessano con Bornago, Gessate, Pozzuolo Martesana, Liscate, Paullo and Vizzolo Predabissi).
In addition to the motorway route, the design includes 19 modifications of the interconnected secondary road system ('related works') in order to upgrade and implement the major existing crossing roads, providing an infrastructure fully integrated in the territory and significantly improving the road standards and connections between primary and secondary network. Therefore, the design phase of the related works has focused on upgrading and improving the major existing roads, connecting them, if necessary, to the new motorway road and facilitating connection of the latter with the relevant areas in order to decongest the secondary network (otherwise highly penalized).
During the design phase, besides the correct choice of the roadway type (based on the features and conformation of the crossed territory), special attention was paid to environmental protection, with notable works of sound insulation and protection of the hydrographic network and the irrigation canals. In addition, several environmental compensations have been introduced, with several areas turned into green spaces with naturalistic function, a proper 'soft mobility' and the identification and design of new footway and cycle lanes.
