Mexican Federal Highways
The Chiapas Bridge (Puente Chiapas in Spanish) is a steel bridge over a kilometer in length which spans the Nezahualcoyotl or Malpaso Dam in northern Chiapas, Mexico. Construction of the bridge began in 2002 and finished fourteen months later, voted the best infrastructure project in Mexico in 2004. The bridge and the highway it is part of cuts driving time from Mexico City to the state capital by 3.5 hours and makes the rural area in northern Chiapas more accessible and open to ecotourism.
The bridge was built by the Secretaria de Comunicaciones y Transportes as part of an upgrade in the highway system designed to integrate the state of Chiapas more into the rest of the country. The highway links Las Choapas in southern Veracruz to Tuxtla Gutiérrez. The new road cuts 3.5 hours off the drive from Mexico City to Tuxtla Gutierrez, and the reduced the driving distance over 100km to 861km. It also allows the north of Chiapas near Veracruz and Tabasco to be more accessible.
The Federal Electoral Districts of Mexico (Spanish: Distritos Electorales Federales) are the 300 constituencies or electoral districts into which Mexico is divided for the purpose of federal elections. Each district returns one Federal Deputy, who sits in the Chamber of Deputies, the lower house of the Federal Congress. An additional 200 deputies are elected by proportional representation.
Electoral districts are identified by roman numerals and by federal entity (state or the Federal District). The number of electoral districts was set at 300 in 1979, when the number of seats in the Chamber of Deputies was increased from 196. The demarcation of the districts depends on the results of the previous electoral census, and adjustments to the 1979 districts were made in 1996 and 2005.
The geography of Mexico describes the geographic features of Mexico, a country in the Americas. Mexico is located at about 23° N and 102° W in the southern portion of North America. It is also located in a region known as Middle America. From its farthest land points, Mexico is a little over 3,200 km (2,000 mi) in length. Mexico is bounded to the north by the United States (specifically, from west to east, by California, Arizona, New Mexico, and Texas), to the west and south by the Pacific Ocean, to the east by the Gulf of Mexico, and to the southeast by Belize, Guatemala, and the Caribbean Sea. The northernmost constituent of Latin America, it is the most populous Spanish-speaking country in the world. Mexico is three times the size of Texas.
Almost all of Mexico is on the North American Plate, with small parts of the Baja California Peninsula in the northwest on the Pacific and Cocos Plates. Some geographers include the portion east of the Isthmus of Tehuantepec including the Yucatán Peninsula within North America. This portion includes Campeche, Chiapas, Tabasco, Quintana Roo, and Yucatán, representing 12.1 percent of the country's total area. Alternatively, the Trans-Mexican Volcanic Belt may be said to delimit the region physiographically on the north. Geopolitically, Mexico is generally not considered part of Central America. Politically, Mexico is divided into thirty-one states and a federal district, which serves as the national capital.
