Interstate 410
Interstate Highway in Texas, United States
Interstate 410 (I-410), colloquially Loop 410, is an auxiliary route of I-10 around San Antonio, Texas. It is identified as the Connally Loop in honor of former Texas Governor John Connally.
Route description
I-410 circumnavigates the city of San Antonio, officially beginning and ending at the junction with I-35 on the southwest side of the loop. There are vast differences between the northern arc and southern arc of the loop. The northern arc serves the heavily urbanized portions of San Antonio and is currently being widened to as many as five lanes in each direction. The southern arc resembles more of a rural Interstate as it transverses, for the most part, undeveloped portions of San Antonio as a four-lane Interstate. I-410 intersects I-10 twice, I-35 twice, I-37 once, as well as U.S. Highway 90 (US 90), US 281, and State Highway 151 (SH 151), all freeways in Greater San Antonio with the exception of Loop 1604, which forms a secondary loop around the city, and Wurzbach Parkway, which is located about two miles (3.2 km) outside the loop on the north side. I-410 serves San Antonio International Airport, Lackland Air Force Base, Fort Sam Houston, the South Texas Medical Center, Southwest Research Institute, and Toyota Motor Manufacturing Texas.
History
Like most cities in Texas, San Antonio was served by a loop around the city long before the arrival of the Interstate Highway System. Loop 13, although not a freeway, served in this role up until the 1950s, when many of San Antonio's freeways were constructed.
This brief starts where responsible research should: with the source description of “Interstate 410” as interstate Highway in Texas, United States. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as interstate Highway in Texas, United States. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Nov 10, 2025. The linked authority identifier is Q2451115. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1604.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
