- The bypass is a great shortcut of 1.5 kilometers, an alternative to the 260,000 vehicles a day that travel the southern arc, 30% of which (80,000) will use
- The 30th Street project removes the barrier to the south and west, the river recovers, sets the stage for a park of one million m2, reduce accidents by more than 50% and eliminates 35,000 tons of greenhouse gases this year
- Investment in the underground bypass on a South amounts to 551.9 million euros, while the set of actions that the mayor opened today amounts to 622 700 000
- The tunnel has the most advanced security systems, by the Tunnel Control Center Calle 30: 92 cameras, 21 message signs, 374 speakers and 19 emergency exits
- So far 270,000 trees have been planted related to reform, not only in the districts through which runs Calle 30, also in other
The day has come!
Among the many achievements that includes the reform of the M-30 include reduced traffic in the city, which allows spaces that will recover make it more habitable. From a new Cuesta de Moyano pedestrian Plaza de Santo Domingo, passing along the boulevard on Avenida de Portugal, or the streets open to pedestrians as Arenal, Montera, Fuencarraland O ‘ Donnell .
The 30th Street project has been a great effort to improve the competitiveness of Madrid and the quality of life of its citizens. Removes the barrier with the South and West recovered the river, provides the basis for a park of one million m2, reduce accidents by more than 50%, eliminating 35,000 tons of greenhouse gases this year, has allowedpedestrianise many areas, “and improved mobility for short trips and restore public the most precious: time.”
Benefits are for the whole of the city, especially for the one million residents who live in the five districts closest to river.
South Tunnel Details Bypass
The new underground North joins South, which opened in March, and gives full functionality of this alternative route that solves, with Ambassadors connection with the A-4 and M-40, South Node problems, the most congested and dangerous of the old M-30. The tunnel from west to east has two entrances . The first , through the underground river system up to the Vicente Calderon stadium, by a stretch of 1.6 kilometers underground. This leads to the bypass , which emerges in the M-30 at the height of the strip of the Mediterranean, or in the A-3.
And the second access , through spur Marqués de Vadillo , also opened this morning. In total, nearly 6 miles of underground track, along the stretch from Portugal Avenue, become 12: “the longest urban tunnel in the world.”
Investment in the underground bypass in South direction amounts to 551, 9 million euros, although the set of actions that the mayor opened today amounts to 622.7 million. To materialize have been used the most advanced: the TBM has excavated and lined Tizona 3.6 kilometers of tunnel in six months and the Security Center Control Works and Infrastructure, 1911 prepared with sensors to monitor the slightest impact, not detected none.
tunnel itself has the most advanced security systems, which are in charge of the Tunnel Control Center Calle 30: 92 cameras, 21 message signs, 374 speakers and 19 emergency exits and connections North tunnel and a lower road assistance vehicle.
A great shortcut
The bypass set a great shortcut of 1.5 kilometers, an alternative to the 260,000 vehicles a day that travel the southern arc, 30% of which (80,000) will be used. The City Council also expects a reduction in accidents of 53%, and a great improvement in the environmental quality of the residents of Legazpi , Bridge Vallecas and Usera , due to traffic flow and particle filtering systems, which retain 80%.
Currently 270,000 trees have been planted related to reform, not only in the districts through which runs Calle 30, also in twelve districts.
To get to this day the 30th Street project “has exceeded more obstacles that no other infrastructure in Spain “by the best engineers, workers and businesses. For the 5,200 workers who have come to participate in the works simultaneously creating added 60,000 jobs, an investment that will generate 23,000 more, and this work will give Madrid a return of 1.79 euros for every euro invested.

The M30 project AIMS to solve the problems of gridlock on Madrid’s roads by refurbishing the road and running major sections of it beneath the city, creating new parkland and riverside above. A total of 99km of new road and 56km of tunnel will Have Been constructed by the time the project is completed. With an Estimated budget of € 3.7 billion and completion date (already behind) of mid-2007, this is a major undertaking!
The M30 Madrid Project is so massive That not less than seven Earth Pressure Balanced (EPB) Tunnel Boring Machines (TBMs) of various specifications Have Been Specially ordered for the 15 separate projects around the city.
one such machine came from German firm Herrenknecht AG. It was too massive to transport whole and had to be reassembled on site.With an immense 15m diameter and weighing 4000-tonnes, it surpassed its expected 300m per month progress and Achieved 500m per month (36m per day) – finishing its tunnel ahead of schedule. In August 2006, a similarly-proportioned machine from Mitsubishi Heavy Industries and Spanish company Duro Felguera beat this record by 40m Achieving progress in a single day.

If pinchais any picture you come into a slide within the TBM , quality feel but without tripod and without light is complicated.
