## Demographics

## Roadway

La Rumorosa also refers to the famous road that crosses the Sierra de Juárez Mountains in Baja California, which is part of Mexican Federal Highway 2D. This was completed in 1917 under the governorship of Esteban Cantu. Before this road was constructed, land travel between Tijuana and the rest of Mexico required travel through the United States.
Initially, this road was a two-way street only somewhat dangerous due to the wind in the region and the steep grade of the road, as well as the recklessness of some drivers to try to finish this stretch of highway faster, causing numerous accidents. Currently there are two two-lane roads each, one upstream and the other downstream, with improved marking and consequently, a significant reduction of accidents.
However, even with security measures, the road is still considered one of the most dangerous for inexperienced drivers, so it is always advisable to observe a minimum safe distance, to not exceed the speed limit, and use engine braking whenever possible. Headlights are advised in adverse conditions.
