In 2005, a road was built between El Llano de Huaxquilico to San Pedro Escanela, but it is controversial because of environmental concerns. Its building caused severe ecological damage in an area considered to be one of the most sensitive in the Sierra Gorda Biosphere Reserve, as it is where most of the local aquifers recharge. The area receives a large amount of rain, which has led to damage and mudslides affecting the road, making it almost impossible for more than one car to pass at a time.
