Roads to Alcochete: what is planned, and what is still unclear

The road plans are among the most concrete-sounding parts of the July 2026 announcement, and among the least documented.

Getting to the airport: the proposed numbers

Road traffic expected each day · 65,000 light vehicles · about 2,000 heavy vehicles

Each icon = 1,000 vehicles a day. Red: heavy goods vehicles.

Estimates from the July 2026 proposals. Rail, the Third Tagus Crossing and the roads each need their own decisions. Data as of 18 October 2026, from the linked records. Graphic: Luís de Camões Airport Observatory (original work).

The numbers

The Government’s summary lists 250 km of new roads and more than 50 km of upgrades to the existing network, sized for an estimated 65,000 light vehicles and about 2,000 heavy vehicles a day. ANA’s release says ‘more than 250 km’ of new roads. The difference is small, but it is a difference, so we show both.

The schemes

  • Links from the EN4, EN10 and EN119 to the airport.
  • Connecting the A33 to the A12 and the A13.
  • The IC13 between the airport, Ponte de Sor and Alter do Chão.
  • Dualling the EN118 and improving the EN119, to strengthen links between municipalities on both banks of the Tagus.

What is missing

For each scheme: who owns it, who pays, whether it needs its own environmental assessment, and when it will be built. None of that is in the sources we reviewed, so each is recorded as a proposal.
