“"This work is fundamental for two key reasons. The first is that it facilitates access and safety to the Observatory, a benchmark in Europe where we can admire the cleanest sky on the Continent. An enclave that has become a draw for the 'Costa de Almería' destination and one of our pillars of industrial tourism. And, secondly, because the renewed surface of this road will be inaugurated with the finish of Stage 12 of the Vuelta Ciclista a España, one of the most demanding and exciting stages of this edition."

Renovated road towards the Calar Alto Observatory in Almería.
The A-1178 road, connecting Gérgal, Bacares, and Olula de Castro to the Calar Alto Astronomical Observatory, has been rehabilitated by the Provincial Council of Almería with an investment of 340,000 euros, just in time to host the finish of Stage 12 of the Vuelta a España.
The Provincial Council of Almería has completed improvement and rehabilitation works on the regional road A-1178, a vital route linking the municipalities of Gérgal, Bacares, and Olula de Castro with the Calar Alto Astronomical Observatory. This project, representing a provincial investment of 340,000 euros, renews a 4.15-kilometer stretch, enhancing safety and access to this scientific and tourist hub.
The road, which was in a state of significant deterioration, has received a new 5 cm asphalt overlay, improved rainwater drainage, and fresh road markings. The intervention aims to facilitate access to the observatory, recognized for having one of the clearest skies in Europe and serving as a pillar for industrial tourism, while also connecting the territory and improving infrastructure for the involved municipalities.
The newly paved road will debut on September 3rd with the finish of Stage 12 of the Vuelta Ciclista a España. This stage, one of the edition's most challenging, will conclude at Calar Alto, over 2,100 meters above sea level, marking the highest finish of the race. The competition, broadcast in 190 countries, is expected to provide significant media exposure for the infrastructure upgrade.
The director of the Calar Alto Astronomical Observatory, Jesús Aceituno, thanked the Provincial Council of Almería and the involved town councils for their efforts, noting that the road now matches the center's international prestige. The mayors of Bacares, Olula de Castro, and Gérgal also expressed their satisfaction with the project, highlighting its importance for tourism, science, research, and the safety of residents and visitors.
Stage 12 of La Vuelta, spanning 167 km with over 4,500 meters of cumulative elevation gain, will feature four major climbs before the summit finish at Calar Alto. The cycling event is renowned for its extensive media reach, attracting millions of viewers and significant media coverage.
