The TEEM Executive Project was designed to ensure the Bypass fits seamlessly into a landscape dominated by some major and numerous minor watercourses. To achieve this, a significant amount of engineering will be done to ensure a positive “relationship” with the plentiful water. A number of activities will also focus on supporting the various entities that manage these watercourses to maintain or even regenerate the functionality of the entire water and irrigation network. Likewise, effort will be made to ensure the work done respects the local environment. In total, over the entire area crossed by the Milan Outer Eastern Bypass (TEEM) and the ancillary works, 120 hydraulic projects will be undertaken.

The Bypass will cross the main rivers with three bridges and a viaduct. Moreover, any time the infrastructure “impedes” the system of canals and waterways, these problems will be resolved by creating water channels or deviations. For the more complex issues, the Bypass and related infrastructure will include water canals and passageways for the local fauna, thus ensuring the preservation of the local ecosystem. Over much of this area, the water table is so high it actually reaches the surface. As such, specific technical solutions will be adopted to ensure high safety levels for travellers, while simultaneously causing no damage to the water system.

Finally, any rain that falls on the Bypass will be channelled into a treatment and purification grid, thus preventing the dispersion of pollutants. As part of this, rainwater collection areas and 6 tanks will be created to receive water from precipitation, and a network of pipes will service the entire 32 km of the motorway-grade road.
