M-70: 3D Modeling to Decongest Madrid with the Pentagon Project

Published on April 30, 2026 | Translated from Spanish

The M-70, or Pentagon Project, reemerges as a road solution to eliminate through traffic in Madrid. This highway would connect the bordering provincial capitals (Segovia, Ávila, Toledo, and Guadalajara) without crossing the community. The route, conceived 20 years ago, aims to close the northern ring of the M-50 and link radial highways such as the A-1 and A-6, optimizing logistics flows and reducing congestion on the M-30 and M-40.

To analyze the impact of the M-70, a 3D model of the pentagonal route connecting the A-1, A-2, A-3, A-4, A-5, and A-6 highways is proposed. The simulation should represent the current vehicle density on the M-30 and M-40, contrasting it with the future peripheral network. Exchange nodes will be modeled in the provincial capitals, calculating transit times and detours for transport fleets. Comparative animations will show the reduction of bottlenecks south of the M-50, allowing planners to visualize the optimization of long-distance routes without entering the capital.

From the 2008 crisis to smart 3D logistics 🧠

The project, halted by the 2008 crisis, returns to the agenda as a response to current saturation. Modeling the M-70 in 3D not only serves to visualize its route but also to validate scenarios of fuel savings and emissions. If the infrastructure manages to divert through traffic, supply chains between the central peninsula and the north will gain efficiency. The simulation allows anticipating design errors and justifying the investment, turning an old plan into a tactical tool for 21st-century logistics.

How can 3D modeling applied to the design of the M-70 viaduct optimize the manufacturing of its prefabricated modules to reduce on-site assembly times and minimize traffic interruptions during the construction of the Pentagon Project?

(PS: visualizing logistics flows is like watching ants... but with less order and more budget)
