Advancements in the A-5 Burial Project
Construction efforts to transform the Paseo de Extremadura into the Paseo Verde del Suroeste in Madrid have made significant strides. The latest milestone was the successful connection of two tunnel excavation sections, a crucial step in the project. This achievement is gradually alleviating the disruption that has beleaguered local residents for over a year.
Tunnel Connection Achieved
Recently, construction teams completed the connection between two separately drilled tunnel sections, linking 700 linear meters of the underground structure. According to reports from the Madrid City Council, a total of 1.9 kilometers out of the planned 5.1 kilometers have been excavated, with 81.7% of the covering slab already placed. The remaining sections will follow suit in the upcoming weeks.
Timelines and Traffic Management
Borja Carabante, the delegate for Urban Planning, Environment, and Mobility, has stated that the interior of the tunnel is expected to be completed by April 2024, leaving only paving and the installation of essential infrastructure left to complete. The project is scheduled to open to traffic by the end of 2026, adhering to the original deadlines despite various challenges faced over the past year.
Traffic Flow Improvements
In a bid to relieve congestion, recent work has allowed traffic to flow smoothly once again along a 500-meter stretch of the A-5, specifically between kilometer points 3+250 and 3+750. The completion of the covering slabs around the Amusement Park has restored the original road layout, minimizing detours. Furthermore, a new connecting branch is being constructed to streamline traffic between Avenida de Portugal and the A-5.
The Challenges Residents Face
Despite the positive developments, local residents continue to endure significant disruptions. For over a year, complaints have ranged from persistent noise pollution from construction machinery to intermittent water and electricity outages, not to mention a decline in air quality due to dust generated by drilling activities. Arturo Sáez, president of the Batán neighborhood association, described the situation as a “perfect storm,” exacerbated by increased traffic to local attractions like the Amusement Park and Zoo, particularly on weekends.
Communication Disruptions
Residents have also reported recurring internet outages linked to damage to fiber optics, impacting several providers such as Movistar and O2 in areas like Aluche and Campamento. This technical difficulty has added to the frustrations of those near the construction zone.
The Ultimate Vision
The overarching goal of this extensive work is to create the Paseo Verde del Suroeste, a 3.2-kilometer pedestrian corridor that will unify neighborhoods within the Latina district. By reducing surface traffic by up to 90%, the project aims to significantly lower pollution levels and improve air quality. Enhancements will include a new 3.5-kilometer bi-directional bike path, wider sidewalks, and substantially more pedestrian connections—totaling 33, a significant increase from the current 16.
Future Steps
Looking ahead, the most challenging aspect will be connecting the new tunnel to the Portugal Avenue route. Experts anticipate traffic disruptions similar to those experienced in previous summers. Nevertheless, Mr. Carabante remains optimistic, noting that the most difficult phases of the project are behind them. Every day, over 600 workers and 400 machines are actively contributing to the ongoing efforts, steadily pushing towards completion.
As construction progresses, the community’s patience may soon pay off, transforming the once challenging traffic corridor into a green space for all to enjoy.
