Interstate 2 begins west of Mission on US 83 in Texas, which runs north to Laredo. I-2 runs east through the urbanized region along the Rio Grande in deep south Texas. The highway here has largely 2×3 lanes and runs through the cities of McAllen and Pharr. There is an interchange with Interstate 69C in Pharr, running as a half- stack interchange. East of Pharr, the urbanized region is less densely populated and consists of small towns that have grown together along the I-2. This part of the route also has 2×3 lanes with frontage roads. Interstate 2 ends on a half stack with Interstate 69E in Harlingen.

The highway was originally numbered only as US 83 in Texas and ran just west from Harlingen. This road was built as a freeway before the 1980s with Interstate Highway design requirements. Exactly when this happened is not known, but at least somewhere between 1962 and 1995. The highway originally had mostly 2×2 lanes and was later widened to 2×3 lanes, first in McAllen and Pharr in the 1990s, the last part between La Feria and Harlingen in 2009.
On April 1, 2013, the Texas Transportation Commission applied for the Interstate 2 number for US 83 in the Lower Rio Grande Valley. This was approved by the FHWA on May 24, 2013. At the same time, I-69C and I-69E were also approved in this area. The assignment of Interstate 2 to US 83 required no physical changes other than installing I-2 signposts. On July 15, 2013, the first signposts with I-2 were installed in Harlingen and Pharr.
The I-2 is the lowest number of all Interstate Highways. Before 2013, Interstate 4 in Florida was the lowest number. The granting of I-2 and I-69C and I-69E meant that South Texas got Interstate Highways for the first time, even though this region is not yet directly connected to the Interstate Highway network.
A concrete project is the bypass of La Joya. This will extend I-2 11 kilometers west, although the project name is referred to as the ‘US 83 Relief Route’. The project was initially estimated at $96 million, but later it was said to be $200 million. Construction was supposed to start in 2016, but was delayed due to a design change. Construction began in 2019 with the frontage roads over La Joya Lake. Construction progressed throughout 2020-2021 and is due to open in early 2023.
More west, the Loop 195 is planned around Rio Grande City. This may become part of I-2 in the future.
44,000 vehicles drive daily in Palmview, rising to 144,000 vehicles on the busiest section in McAllen. There were 135,000 vehicles east of I-69C in Pharr, dropping to 90,000 vehicles east of Pharr. The quietest part between Pharr and Harlingen has 56,000 vehicles, then rising again to 78,000 vehicles for the I-69E in Harlingen.
Interstate 110 in Texas
Interstate 110 or I -110 is an Interstate Highway in the US state of Texas. I-110 forms a short connection to the border with Mexico in the city of El Paso and is less than a mile long.
I-110 is part of the Patriot Freeway, a north-south highway in El Paso made up mostly of US 54. The section between I-10 and the border crossing with Mexico is numbered I-110. The highway has two to three lanes in each direction and first forms a parallel structure south of I-10 with US 54. This bends as if to a sunken location under US 62, after which I-110 ends at the border crossing with Mexico, which becomes formed by the Bridge of the Americas over the Rio Grande. The Carretera federal 45 in Mexico then continues through Ciudad Juárez.
I-110 was added to the planned network of Interstate Highways in 1967. The highway was then opened to traffic in phases between 1970 and 1973 and was constructed from south to north. I-110 was originally an unsigned Interstate Highway, the number did not appear on signposts and trailblazers until 2010.
I-110 is one of the shortest waymarked Interstate Highways in the United States, the only one that leads a 3-digit Interstate Highway to the border with Mexico and only one of two 3-digit Interstate Highways that lead to a border crossing, the other being the Interstate 190 at New York.
Every day, 69,000 vehicles drive on the section that coincides with US 54, between I-10 and the fork of US 54. The section between US 62 and the border crossing handles 28,000 vehicles per day.
