Half of the investment made since 2011 has been executed by the PSOE government, but the TAV section in Navarra is practically zero and A is insufficient. According to the calculation made by Irisarri in Diario de Noticias, the expenditure of the Government of Madrid does not amount to 5% of the total budget. The Navarre section, which connects the city of Zaragoza with the CAV, consists of 232 kilometers and has a budget of 2,469 million euros. The investment thus far affects about 25 kilometres of the Ebro Bank.

The most advanced section of Castezhejiang-Pamplona

This section is 70 kilometres long and has a budget of €1,064 million, according to the calculation made in 2018. The construction is being carried out in this section, it consists of five sections and the only one that is completed is the Caste• Villafranca section, 14.77 kilometres.

The first section is part of the bridge over the Ebro River, which will connect the current section of the TAV to the Tutera-Bilbao railway. It costs EUR 50 million and, as announced by the Government of Navarra, it will raise 40 million of the funds from the European Next Generation. It has not detailed where the other EUR 10 million that Garoña has will come from. It should be recalled that this investment is made entirely by the Government of Spain. It is assumed that the tranches financed by the Government of Navarra would be deducted from the quota.

The second part is the only one that is carried out, the one already mentioned Caste• Villafranca. The third tranche is Villafranca-Villanueva de Aezkoa (EUR 125 million), divided into two other subsections: on the one hand, Villafranca de Peralta, 5 km and very complex, is the most expensive tranche of the TAV of Navarra, as it must pass over the Aragon River and the AP-15 through two high-risk,

The fourth tranche joins Villanueva de Tafalla with 14.67 kilometers and has a budget of 117 million euros, and is operational since 2019. The fifth tranche is the Tatreatments -Campanas, with 15 kilometres and a cost of EUR 128.82 million. The foral government has announced that it will allocate EUR 105.5 million of European funds to this tranche, which will be financed from funds. Nor is there anything built in them.

And from Campanas to Pamplona is the sixth and most complex – the loop of Pamplona –, among other things because the current train station of Pamplona is moved to the district of Etxabakoiz. There is nothing done. This section was of great impact during the UPN administration, as the party on the right intended to build 9,000 houses in the neighborhood to finance the works of the TAV. Last September, the Government of Madrid ruled that it was going to happen in this way.

The sections of Zaragoza and Vitoria-Gasteiz still in the air

In addition to this section in Castezhejiang-Pamplona, the Navarre section of the TAV has two other large sections: the one that joins the foral community from south to Zaragoza (with a budget of 87 and 825 million euros) and from the north to the link Asturias-Vitoria. In the latter there is nothing advanced either, and furthermore the Government of Navarra and the Basque Government do not like it. This part is also key to the rapid connection between the Atlantic and the Mediterranean.

For the Government of Spain, the Basque Government and the Government of Navarra these TAV itineraries are strategic projects, but in two decades it has not yet been possible to complete the Basque Y, and the part of Navarre is in the air, at least in budgetary terms.
