Tramo 1 of Avenida Constitución Reopens

The stretch of Avenida Constitución between Avinguda 302 and Avinguda Pineda has reopened to vehicles, marking progress in the ongoing transformation of the C-245 through Castelldefels. This section, known as Tramo 1, now allows traffic to flow through connections with Doctor Fleming, Doctor Ferran, Avinguda 300 and Avinguda 301.

Major Works on Schedule for Late November, Early December Finish

According to the Ajuntament de Castelldefels, current traffic restrictions on key roads such as Avenida Constitución (Tramos 1 and 3), Santiago Rusiñol and Avinguda dels Banys are on track to be lifted between late November and early December 2026. The works are part of a wider infrastructure upgrade across the town.

New Works on Carrer Barcelona Aim to End Flooding

Separate major works on Carrer Barcelona, between the C-32 motorway and Passeig del Pitort, began in June 2026 and are expected to last seven months. The project, approved on 13 February 2026 by engineering firm SBS Simón i Blanco S.L., aims to eliminate chronic flooding in the area by installing a new stormwater drainage network and pumping station. Additional improvements include full renewal of the road and pavement, installation of energy-efficient LED street lighting, undergrounding of power and telecom lines, and the creation of around 100 new free parking spaces, including a designated row on the Gavà municipal boundary side.
