The agreement to build the entire line 3 of the Metro, reached this month between the Minister of Development of the Board Marifran Carazo (PP) and the mayor of Seville Juan Espadas (PSOE), is hopeful. Both leaders have ratified the technical reports that advise adding three new stops to the construction project that had been in the drawer for eight years.
“We cannot guarantee that something (of the 2011 project) will not change due to regulations and technical advances”, clarifies Development.
The original project will be updated between the end of this year and throughout 2020 with a budget of one million euros. When it is ready, the financing will be discussed with the State and the start of works (where to start and the chronology of its execution) with the commitment to do it seriously and with realistic deadlines.
At the expense of knowing the changes that the original project will undergo with its update (the contract will be awarded at the end of this year and the chosen company will have until autumn 2020 to finish it), it is a good time to remember the details of the 19 stations of line 3 that appear in the 2011 document. The Ministry of Public Works admits that it could undergo modifications. “We cannot guarantee that something will not change due to the new regulations and technical advances,” he clarified this week to this newspaper.
In the original project, the line goes 12 meters deep and no tunnel boring machine is used
Not counting the three new stationsadded after the pact (Hospital de Valme, Bellavista and Palmas Altas), Line 3, which crosses the city from North to South, was proposed with an estimated budget of 1,179 million euros and a forecast demand of 100,268 passengers per day.
Its total length, excluding the workshop and garage branch, was 11.9 km, of which 11.5 km were underground (at an average depth of 12 meters and without a tunnel boring machine , with thescreen-wall technique , which is the work of in the open sky) and 0.4 km on the surface. Its commercial speed was around 25 km/h.
Starting with the South, the new stations that have been added (Hospital de Valme, Bellavista and Palmas Altas) will be designed in the final project resulting from the update. What is planned is that they go on the surface in line with the layout of the two that go on Avenida de Jerez.

Section 1

These are the ones defined in the original construction project, drawn up by the joint venture Ineco-Typsa, Idom and Ingerop. The Bermejales station runs alongAvenida de Jerez on the surface , at the height of Calle Finlandia and 150 meters from the entrance of the Hospital Fremap; and the Pineda station , at the intersection of the avenue with Nuestra Senora del Pilar street.
In the project it was not clear if it would continue on the surface until the exit of the current bridge, which would require replacing said bridge with another with sufficient capacity to support road and rail traffic. Once past the intersection, the line descends with a slope of 60% so that it can go along the underground Avenida de la Palmera.

Section 2 Section

2 runs from La Palmera to Doctor Fedriani Avenue. It starts underground on Avenida de la Palmera , at a depth of 12 meters compared to street level. Three stations are located here : Heliopolis , at the end of the line, in front of the Betis Manuel Ruiz de Lopera stadium; La Palmera station, after the intersection of the avenue with Marques Luca de Tena street along which the future Line 4 runs; and Bueno Monreal station , just before the intersection with this underpass of the same name. To overcome this underpass, the Metro was planned to be about 14 meters deep, two meters more than the rest of the route.
After Avenida de la Palmera, the line crosses through Eritana to Avenida de La Borbolla . In La Borbolla there are two stations, one at each end: the Parque de Maria Luisa station , in front of the Eritana barracks, and the Plaza de Espana station , in front of the Hotel Melia and Capitania General. The street level is maintained at 12 meters from the street level.
Then the line enters theCarlos V Avenue before reaching the Prado, where there is the highest concentration of physical conditions. Here it intersects with Line 1 of the Metro that runs with a double tunnel for a single track of 5.30 meters in diameter. The Prado de San Sebastian station , according to the original project, should be placed parallel to Line 1 and the Metrocentro, and under the latter. It is attached to the Prado station on Line 1 to achieve the best passenger exchange.
The Maria Auxiliadora station, in the historic round, goes right in front of the health center
After crossing the Tagarete stream, line 3 accesses the Historic Round at the same street level of 12 meters. On Menendez Pelayo avenue there are twostations: Jardines de Murillo , in front of the Provincial Council; and Puerta de Carmona station , in front of the La Florida building, before the intersection with Luis Montoto.
Continue towards Maria Auxiliadora avenue and right in front of the health center is the Maria Auxiliadora station . At this point the intersection with line 2 takes place (on its way from Jose Laguillo street to the center), which runs through here at a depth of 49 meters with respect to street level.
Once it reaches the roundabout of Capuchinos, the project places the Capuchinos station between Cruz Roja avenue and San Hermenegildo street.
And on Munoz Leon street the station La Macarena is projected, in front of the wall and at the height of Sanchez Perrier street. It is the last stop of the Historic Round.
From here the line turns towards Doctor Fedriani avenue , where the tunnel must cross under the Macarena car park, which requires a descent of 8 meters with respect to the level planned in the Ronda Historica. The Virgen Macarena Hospital station is located on the opposite corner of the hospital located in El Cerezo. Here line 3 intersects with line 4, and this station marks the end of section 2.

Section 3

This section finally runs entirely underground from Doctor Fedriani to the Glorieta de San Lazaro, parallel to the Ronda Urbana Norte . There are two stations here: San Lazaro, at the height of Blasco Ibanez street, and the SE-30 funeral home; and Los Carteros station (formerly Poligono Norte), at the height of Parque Norte and Camino Cantalobos street.
It is necessary to execute an underpass at the intersection with Avenida Alcalde Manuel del Valle and continue under the right service road of the Ronda Norte until the intersection of the Metro line under the Ronda Urbana Norte.
The line crosses Pino Montano underground. There are three stations in this neighborhood: Los Mares , on Mar de Alboran street, near the Pino Montano health center; the Pino Montano station , on Agricultores street at the height of Estrella Betelgueuse street, and Pino Montano Norte(in the Higueron area)

The most complicated points

In 2012 it was announced that the most complicated points on the line are those that cross the intersection with already built underground structures: the Bueno Monreal underpass, the line 1 tunnel in the Enramadilla, and the Macarena car park.
The idea is that the works of each section require no more than three years , according to the calculations that were announced in 2012, with which it would be convenient to start at both ends of the line at the same time so as not to delay the need that the capital has. of this transport.
Minister Carazo and the mayor hope that we can see the first works before the municipal mandate of Espadas ends. If the projects are ready in 2020, their adjudication would remain and that means that we should see works between 2021 and 2022.
