Brisav Sends the RECAPE for Porto-Oiã High-Speed Rail Sections 4 and 5 Out to Public Consultation From 8 June — 15 Working Days on the Participa Portal Test the Gaia Station Move to Vilar do Paraíso and the Twin-Bridge Douro Crossing

The Brisav concessionaire opens the public-consultation window on the Relatório de Conformidade Ambiental do Projeto de Execução (RECAPE, Environmental Compliance Report of the Execution Project) for subsections 4 and 5 of the Porto — Oiã stretch of the new linha ferroviária de alta velocidade on Monday 8 June 2026. The Participa portal carries the file for 15 working days, closing on 29 June. It is the gating step the Agência Portuguesa do Ambiente (APA, Portuguese Environment Agency) demanded after rejecting the original execution project in December 2025 — a refusal that put two of the most politically loaded decisions on the entire Porto–Lisboa line back on the table.

What Subsections 4 and 5 Cover

The Porto — Oiã stretch terminates the high-speed network's first phase on the Aveiro side and feeds the future Aveiro — Coimbra and Coimbra — Lisboa segments. Subsection 4 covers the urban approach into Vila Nova de Gaia, including the Douro crossing and the Gaia station; subsection 5 carries the line south through the Espinho corridor. APA's December 2025 declaração de impacte ambiental refused the package on two grounds. First, Brisav's choice to relocate the Gaia station from the long-planned Devesas site to Vilar do Paraíso. Second, the concessionaire's preference for two separate single-purpose bridges over the Douro — one road, one rail — instead of the combined road-rail crossing that anchored every previous iteration of the project since 2009.

Why the Two Decisions Matter

The Gaia station siting fight is a thirty-year debate in the local press. Devesas plugs directly into the existing CP Linha do Norte interface and into the Metro do Porto Yellow Line at General Torres, both of which the município de Gaia and the Comunidade Intermunicipal do Porto have spent more than a decade pushing as the multimodal anchor of the south-Douro hub. Vilar do Paraíso sits further inland, on the A1/IC1 corridor, and is the option Brisav says is cheaper to build and faster to deliver — but it strands the high-speed product from the suburban network unless a dedicated shuttle is engineered into the operating concept.

The twin-bridge question is heavier still. A single combined road-rail bridge would carry both the high-speed line and a relief road for the Ponte do Freixo. Two separate spans, in Brisav's framing, simplify the construction sequencing and let the rail bridge be procured and delivered without waiting on the road authorisations. Critics, including several engineering bodies, argue the optical and environmental footprint of two structures across the Douro is substantially heavier and that the cost saving is, on the consortium's own numbers, marginal once interface engineering at the abutments is priced in.

What Happens Next

• Participa portal, 8 to 29 June. Comments load directly into the public record APA must address before issuing a new declaração de impacte ambiental.
• APA decision window. The agency typically takes 50 working days from consultation close — putting a fresh ruling on track for mid- to late-September 2026.
• Procurement clock. Brisav cannot release the civil-works tranches for subsections 4 and 5 until APA signs a favourable DIA. A repeat refusal sends the consortium back to a redesign and pushes the 2030 opening window into the second half of the decade.
• Politics. The Câmara de Vila Nova de Gaia, the Comunidade Intermunicipal do Porto and the Assembleia da República transport committee have already signalled they will file formal positions during the 15-day window.

Brisav has framed the consultation as a procedural step, not a reopening of the underlying design. The portal record, the Participa submissions and APA's eventual ruling will decide whether that framing holds — and whether the high-speed network reaches the Douro on the timetable the Plano Ferroviário Nacional has been promising since 2024.
