It is part of the San Juan-Caguas-Guaynabo Metropolitan Statistical Area. - Puerto Rico Highway 30 (PR-30), known as Expreso Cruz Ortiz Stella, is a main freeway in Puerto Rico which connects the city of Caguas to the town of Humacao. - The International Boundary and Water Commission is an international body created by the United States and Mexico in 1889 to apply the rules for determining the location of their international boundary when meandering rivers transferred tracts of land from one bank to the other, as established under the Convention of November 12, 1884. - Colorado is a state in the United States encompassing most of the Southern Rocky Mountains as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains.

It begins in downtown of Canovanas , very close to Puerto Rico Highway 3 and ends in Puerto Rico Highway 952 and Puerto Rico Highway 30 in Juncos . For people coming from / going to Caguas , the highway has a direct intersection with PR - 30 ; for those coming from / going to Humacao , drivers have to take short highway PR - 952 and then take PR - 189 just before its intersection with PR - 30 , hence this exit being one of the most disorganized junctions in the island between a main highway and a main freeway or tollway in the island . New Puerto Rico Highway 66 also has a poor - designed intersection with the highway , since it only allow people going to / coming from Carolina ( west ) and not the east . This is probably because the short segment open from the new tollway immediately ends at PR - 3 only 2 kilometers from the exit to PR - 185 and thus expected to be fixed when the segment to Rio Grande opens to the public . The highway enters a small portion of Carolina , before it enters Canovanas . PR - 185 serves as an alternate route for people who drive the way between the metro area and the southeast , and it does not climb many hills and is generally wide . It is a much better option than taking Puerto Rico Highway 181 or going to Fajardo and then go south via PR - 53 , since the island is wider in the north than in the south segment . - Puerto Rico Highway 66 (unsigned Interstate PR3) is a main tollway which parallels Puerto Rico Highway 3 going from the city of Carolina, Puerto Rico via a 3 loops cloverleaf interchange with PR-26 and PR-3, a major exit in the form of a Trumpet interchange in Canovanas, Puerto Rico and ending in the municipality of Rio Grande, Puerto Rico with an intersection of PR-3. It is only long and has very few exits, which work mainly to minimize traffic in the congested Carolina area of PR-3. - The Rio Grande (or or simply Rio Bravo) is one of the principal rivers in the southwest United States and northern Mexico (the other being the Colorado River). The Rio Grande begins in south-central Colorado in the United States and flows to the Gulf of Mexico. Along the way, it forms part of the MexicoUnited States border. According to the International Boundary and Water Commission, its total length was in the late 1980s, though course shifts occasionally result in length changes. Depending on how it is measured, the Rio Grande is the fourth- or fifth-longest river system in North America. - Puerto Rico Highway 3 (PR-3) at nearly 101 miles long, is the second longest highway on Puerto Rico (after PR-2). It connects the San Juan neighborhood of Rio Piedras to downtown Salinas indirectly around the eastern coast of the island. Highway 3 ranges from a three lane urban avenue in San Juan to a one lane rural road past Fajardo.While other roads connect San Juan It runs the coastline of Puerto Rico east of San Juan, beginning in Rio Piedras near Santurce (where it is known as the Avenida 65 de Infanteria) and goes to Fajardo where it goes south paralleling the coastline to Humacao and Maunabo. It goes up to a mountain-scenic route and goes west to Salinas, where it meets PR-1. - The MexicoUnited States border is an international border separating Mexico and the United States, from California in the west to Texas in the east. The border traverses a variety of terrains, ranging from major urban areas to uninhabitable deserts, and is the most frequently crossed in the world, with approximately 350 million legal crossings annually (2010). - Carolina is a municipality located on the northeast coast of Puerto Rico.

In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. - A cloverleaf interchange is a two-level interchange in which left turns ("reverse directions in left-driving regions"), are handled by ramp roads (US: ramps, UK: slip roads). To go left (in right-hand traffic), vehicles first continue as one road passes over or under the other, then exit right onto a one-way three-fourths loop ramp (270) and merge onto the intersecting road. The objective of a cloverleaf is to allow two highways to cross without the need for any traffic to be stopped by red lights, even for left and right turns. The limiting factor in the capacity of a cloverleaf interchange is traffic weaving. - Puerto Rico, (Spanish for "Rich Port") officially the Commonwealth of Puerto Rico ("Free Associated State of Puerto Rico") and briefly called Porto Rico, is an unincorporated territory of the United States located in the northeast Caribbean Sea. - Rio Grande ("Big River") is a municipality of Puerto Rico located in the Northern Coastal Valley, north of Las Piedras, Naguabo and Ceiba; east of Loiza and Canovanas and west of Luquillo.

Starting in the central Rocky Mountains in the U.S., the river flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the ArizonaNevada border, where it turns south toward the international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California between Baja California and Sonora. - The Gulf of Mexico is an ocean basin largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States, on the southwest and south by Mexico, and on the southeast by Cuba. The U.S. states of Alabama, Florida, Louisiana, Mississippi and Texas border the Gulf on the north, which are often referred to as the "Third Coast" in comparison with the U.S. Atlantic and Pacific coasts, or sometimes the "south coast", in juxtaposition to the Great Lakes region being the "north coast." One of the gulf's seven main areas is the Gulf of Mexico basin. - Canovanas is a municipality in Puerto Rico, located in the northeastern region, north of Juncos and Las Piedras; south of Loiza; east of Carolina; and west of Rio Grande.
