According to act-test-centers, State Route 423 is a state route in the U.S. state of New Mexico. The road forms an east-west route through northern Albuquerque and is 17 miles long. The road is also known as Paseo Del Norte
State Route 423 begins in northwest Albuquerque at an intersection with Golf Course Road. The road called Paseo Del Norte begins even further west just outside the urban area. The road heads east and is a 2×3 lane expressway to Interstate 25. There is a bridge over the Rio Grande. East of I-25, Paseo Del Norte is a major city boulevard with 2×3 lanes and traffic lights.
In the 1980s, Paseo Del Norte was not very important, only the part between Coors Boulevard and I-25 had separate carriageways at the time, but only over Coors Boulevard was a grade separated connection, the rest was at ground level. The connection with 2nd Street was realized in about 1994. In the late 1990s, the road east of I-25 was widened from 1×2 lanes to 2×3 lanes with traffic lights to accommodate the growth of the urban area. On July 28, 2014, the connection with Jefferson Street opened.
Between summer 2013 and December 15, 2014, a junction with I-25 was realized, with flyovers from south to west and vice versa. These handle the heaviest traffic flows. The project cost $93 million.
In 2012, 26,700 vehicles drove daily on the westernmost section, rising to 79,100 vehicles on the bridge over the Rio Grande and 60,600 vehicles west of I-25. 43,300 vehicles drove east of I-25, dropping to 11,000 on the easternmost section.
Mountain Passes in New Mexico
This is an overview of mountain passes in New Mexico above 2,000 meters in elevation.
Most of the high mountain passes are located in northern New Mexico, where the east-west routes run through the chains of the Rocky Mountains. The highest tarmac road is the route to Sandia Crest above the city of Albuquerque, at 3,255 feet. The unnamed US 64 Summit in northern New Mexico is the highest thoroughfare. There are plenty of other insignificant mountain passes in New Mexico. The highest highway is Raton Pass on the Colorado border at 2,377 feet. Because the mountain ranges in New Mexico are not as elongated as in Colorado, there are many opportunities to get around the mountains. As a result, there are relatively few classic mountain passes that are the lowest point between two mountain peaks.
Little is known about the history of the mountain passes in New Mexico. The first are believed to have been discovered by Spaniards in the 17th or 18th century and later used by migrants. In particular, the Santa Fe Trail over Raton Pass was of interest. In the American Civil War, an important battle was fought on the Glorieta Pass. In the 1960s, I-25 and I-40 were built over the mountain passes.
|Mountain pass||Route||Height (m)|
|US 64 Summit||3200|
|Palo Flechado Pass||2777|
|Interstate 40 Summit||2217|
Ports to Plains Corridor
The Ports to Plains Corridor.
According to Liuxers, the Ports to Plains Corridor is a series of roads in the United States and a name for a number of planned upgrades to improve connections between the ports on the Gulf of Mexico and the border crossings with Mexico (Port of Entry) with the High Plains. The corridor runs from Laredo, Texas to Denver, Colorado and passes through four states; Texas, New Mexico, Oklahoma and Colorado. The Ports-to-Plains Alliance is a stakeholder group spanning a wider network of roads into Alberta, Canada.
In Texas, the corridor begins in Laredo, a city on the border with Mexico. The route runs through Del Rio, San Angelo, Lubbock and Amarillo to the Oklahoma border. Between San Angelo and Lubbock is an alternate route via Midland, an important oil-producing region. In addition, north of Amarillo, there is a branch to Raton, New Mexico.
The following roads have been designated in Texas as part of the Port to Plains Corridor;
- US 83: Laredo – Carrizo Springs
- US 277: Carrizo Springs – Eagle Pass – Del Rio – San Angelo
- US 87: San Angelo – Big Spring – Lamesa – Lubbock
- SH 158 / SH 349: Sterling City – Midland – Lamesa (alternative route via Midland).
- Interstate 27: Lubbock – Amarillo
- US 287: Amarillo – Stratford – Oklahoma
- US 87: Dumas – Dalhart – Clayton – Raton (New Mexico)
There is a branch line from Amarillo, Texas to Raton, New Mexico. It is formed by US 87 in Texas and US 87 in New Mexico. US 64 also runs on this route between Clayton and Raton. The branch line to Raton provides access to Interstate 25, the highway to Denver. I-25 itself is not formally part of the Port to Plains Corridor.
In the state of Oklahoma, the corridor briefly passes through the Oklahoma Panhandle, via Boise City. Here again the corridor follows US 287 in Oklahoma.
In Colorado, the corridor leads over US 287 in Colorado, via Lamar to Limon. Between Kit Carson and Limon, the route is also double-numbered with US 40. Limon is only a small town, but a well-known point for being the only control city on I-70 from Denver to the east. The corridor therefore also follows Interstate 70 between Limon and Denver.
The Port to Plains Corridor ranges from a single carriageway to a 2×2 divided highway to an Interstate Highway. In Texas, relatively large parts are a 2×2 divided highway or freeway. Elsewhere, the road is still mostly single carriageway. The road mainly leads through flat steppe, the High Plains. The road has a fairly monotonous and boring landscape, in southern Texas the route avoids the scenically attractive Texas Hill Country, although parts of the route between Del Rio and Sonora still have some scenic value.
In the Intermodal Surface Transportation Efficiency Act of 1991, the Ports to Plains Corridor was designated as Corridor 38, a High Priority Corridor of the National Highway System. However, under this law no funding was specifically set for the corridor, nor was a minimum standard set for the corridor. In 2019, a law was passed in Texas authorizing a study for the extension of I-27.
There is no specific plan to upgrade all parts of the route. The chance that this will become an Interstate Highway is very small. The most obvious part that could be upgraded to freeway is between San Angelo and Lubbock in Texas. Elsewhere there are wishes to upgrade the route from Amarillo to Limon. This also coincides with the corridor from Dallas to Denver, which is not formally part of the Port to Plains Corridor between Dallas and Amarillo, but has mostly 2×2 lanes and handles a lot of long-haul traffic. It seems unlikely that large parts of the Port to Plains Corridor will be upgraded in the foreseeable future, since its creation in 1991, upgrades have only been carried out sporadically.
