This painting offers a view of Madrid's Gran Via in 1974, when the first bus lane was inaugurated in the Spanish capital, marking the beginning of a new era in the organisation of urban traffic. The scene shows the avenue packed with cars and buses, whose reflections on the wet asphalt create an iridescent effect that adds dynamism and warmth to the composition. The arrival of the bus lane transformed the flow of traffic on this emblematic Madrid artery, filling the Gran Via with even more life and movement as it adapted to the transport needs of the time.

The facades of the buildings, with their classical architectural styles, frame the scene and highlight the beauty of this emblematic avenue. The colour palette, with warm tones and golden reflections, transports the viewer to an evening or twilight setting where the city seems to be in constant movement. The painting captures the essence of a growing and evolving Madrid, where the Gran Via was the epicentre of modernity and development.

The minute details of each vehicle and building create a nostalgic atmosphere, allowing the viewer to imagine the sound of engines and the hustle and bustle of people on the sidewalks. This piece not only depicts an everyday scene, but also pays homage to a significant moment in Madrid's history, when the introduction of the bus lane symbolized the city's progress and adaptation to the needs of a rapidly changing Spain.
