Interstate 410 or I -410 is an Interstate Highway in the US state of Texas. The highway loops around San Antonio, the state’s second-largest city. The ring road is 80 kilometers long.
Travel directions
I-410 on the south side of San Antonio.
I-410 on the north side of San Antonio.
The highway’s start and end point is in the southwest of the city, at the interchange with Interstate 35. This junction is a cloverleaf with shunting lanes. The highway has only 2×2 lanes here, and leads through a barely built-up area. There are frontage roads along the highway. I-410 slowly turns north, intersecting US 90, the city’s western highway. This node is also a cloverleaf. After this you pass through more urban area, and the ring road has 2×3 lanes. You cross the SH 151. via a junction at the same level for the turning directionsor Stotzer Freeway, a road that is actually more of an expressway than a motorway. Nevertheless, it is an important approach road from the northwestern residential areas.
According to topschoolsintheusa, San Antonio is quite sparsely built up here, with quite a few open spaces in the urban area, so the population density is low. This leads to a corridor with industrial estates along the highway, which are accessible via the frontage roads. A major interchange at the Balcones Heights enclave crosses Interstate 10, which leads to El Paso. One then arrives at the north side of the city, and the highway heads east. There are also business parks here, as well as the airport of San Antonio. The highway has mostly 2×5 lanes along the north side of San Antonio. A full stack interchange crosses US 281, which leads to downtown in the south and some northern suburbs.
After this, the highway runs nearly parallel to I-35 and then turns nearly 180 degrees to parallel Interstate 35 south. After this, both highways run south with 2×3 lanes, which is quite meager given the traffic intensities. At Fort Sam Houston, I-35 exits downtown and continues to Laredo on the Mexican border. The I-410 even only has 2×2 lanes after this. A cloverleaf crosses Interstate 10, which runs east to Houston. There are also 2×2 lanes after this. Crossing Interstate 37. via a 4-level stack junction, which runs to the port city of Corpus Christi. After this the highway turns to the west again, and you have arrived at the south side of the city. The part up to where the highway starts again has 2×2 lanes.
History
Like many Texas cities, San Antonio already had a ring road before the Interstate Highway plan was put into effect. State Route 13, although not a freeway, continued to function as a beltway until the 1950s, when many of the freeways in San Antoniowere constructed. Construction of the ring road began in the 1950s, and the west side of the ring road was completed in 1961, between I-35 and US 281. The ring road was completed in 1967, and in 1969 the road was renumbered Interstate 410. Because the city mainly grew in the north, a widening of the highway was soon necessary, and it was widened to 2×3 lanes in the late 1970s and early 1980s. In 1987 a part was widened to 2×3, and in 1996 a small expansion was completed. done, at Balcones Heights, in the form of one lane heading west.
The north ring was expanded significantly between 2000 and 2010. The north ring originally had 2×3 lanes, the interchange with I-10 was an awkwardly designed series of forks with exits on the left, and the interchange with US 281 only had interchanges via the frontage roads. The large-scale reconstruction started around 2000-2001. The interchange with the many flyovers with I-10 was completed in about 2007. The north ring was also widened to 2×5 lanes and around 2008 the full stack with US 281 was completed. The widening east of US 281 was completed in 2010.
Future
It is planned to convert the connections to US 90 and SH 151 in western San Antonio to a full stack. The interchange with US 90 is a cloverleaf cloverleaf, while at SH 151 all turning traffic goes through traffic lights. On October 9, 2015 the transformation of the interchange with the SH 151 as a stack started. In 2018, the flyovers from west to north and vice versa were put into operation. The reconstruction was completed in early 2022.
In time, much of the western portion of I-410 should be widened from Palo Alto Trail (SH 16) on the south side of San Antonio to Ingram Road on the west side of San Antonio. Also, the clovers with I-35 and US 90 must be replaced by a stack. It is also planned to convert the eastern interchange between I-410 and I-10 into a stack.
