( CNN ) -- Part of a picturesque toll highway that tourists use to travel between the Mexican towns of Ensenada and Tijuana collapsed this weekend , civil protection officials in Mexico said . One of the holes created by the landslide was more than 40 feet deep and stretched 200 feet long . A cement truck was stuck when the ground started shifting , but the driver made it out safely , officials told CNNMexico . The truck ended up tumbling into the Pacific Ocean , which is just west of the road . Officials say it may take as long as a year to repair the damage . Building a temporary road is one option being considered , authorities said . For now , motorists will use a nearby free road . It is unclear what caused the landslide . According to the United States Geological Survey , a magnitude-4.6 earthquake centered about 60 miles southeast of Ensenada struck on December 19 , but the events might not be connected . On the Facebook page of the Baja California Civil Protection services , officials said the road is not in an area where there is a fault line . The damage occurred about 60 miles from Mexico 's border with the United States .
Road is a coastal road that runs between Veracruz and Ensenada . Driver escapes before the truck falls into the ocean . Officials do n't know why road collapsed .
