Pan-American Highway
The Pan-American Highway is a network of roads stretching across the American continents and measuring about in total length. Except for a rainforest break of approximately , called the Darién Gap, the roads link almost all of the Pacific coastal countries of the Americas in a connected highway system. According to "Guinness World Records", the Pan-American Highway is the world's longest "motorable road". However, because of the Darién Gap, it is not possible to cross between South America and Central America with conventional highway vehicles. Without an all-terrain vehicle, it is necessary to circumnavigate this terrestrial stretch by sea.
Mexican Federal Highway 95D
As construction of the highway proceeded in 1991, an archeological site, Cuetlajuchitlán, was discovered, with settlement dating back to 800 BC; the highway travels the Los Querendes Tunnel under the site at a depth of , allowing for its preservation. At kilometer 212, the Mezcala Bridge carries Highway 95D over the Mezcala River; when it opened with the highway, it was the world's tallest bridge. The Autopista del Sol route includes a total of five bridges.
As the road nears Chilpancingo, it comes across a full-access interchange with Highway 95 and Highway 93D, which offer free access to Zumpango del Río and a tolled bypass to Tixtla, respectively; at this interchange, the Dr. Raymundo Abarca Alarcón General Hospital is located, providing medical services in the Chilpancingo area. The Autopista del Sol then cuts south and southeast through the Chilpancingo urban area, passing the campus of the Autonomous University of Guerrero and the offices of the Congress of Guerrero. A set of frontage roads, known as Av. Vicente Guerrero, provides interchanges at local streets, with traffic on free Highway 95 and tolled Highway 95D sharing the route. The two roads split off again in southern Chilpancingo. South of town, travelers encounter the Palo Blanco toll booth, the first in 111 kilometers on the road; continuing toward Acapulco, the highway passes the Guerrero Industrial Park before meeting another interchange at Tierra Colorada, crossing its final bridge, over the , and one more tunnel before turning southwest toward Acapulco. One last toll booth awaits motorists at La Venta, immediately followed by an interchange with Guerrero State Route 200D, the tolled Viaducto Diamante, which connects travelers to the Playa Diamante area southeast of the main city. Soon after, Highway 95 merges into Highway 95D, ending the Autopista del Sol on the northeast edge of Acapulco. Motorists who travel the length of the entire road pay a toll of 324 pesos as of January 2017.
