We need answer via cpa_final_answer commentary, only translated HTML and marker. Need preserve all HTML tags exactly as-is. Translate natural native LatAm Spanish for travelers. Need be meticulous. Input tags: h2, p, strong, em dash entities. Keep tags exact sequence and attributes none. Names/codes unchanged (none codes). Phone URLs none. Need translate heading "Austin to San Antonio drive miles" natural. Could be "Millas en coche de Austin a San Antonio". Native LatAm maybe "Distancia en coche de Austin a San Antonio". But "drive miles" means driving miles. Natural traveler Spanish: "Millas de carretera de Austin a San Antonio". Since destination Spanish context, units miles perhaps "millas en carretera". Need retain 79 road miles as "79 millas en carretera." "between the two downtowns" = entre los centros urbanos de ambas ciudades. em dash entity unchanged? User says keep HTML tags exactly, entities aren't tags. Translation can preserve — and –. We should keep all entities likely. "about 1 hr 30 min" = "aproximadamente 1 h 30 min" perhaps natural. But perhaps retain hr/min? Translation to Spanish: "1 h 30 min". Keep numbers. "via I-35 S" unchanged route. "If you have ever seen a smaller number quoted" = "Si alguna vez viste que indicaban una cifra menor..." "straight-line separation" = distancia en línea recta. "on the ground the highway adds curves, interchanges, and metro frontage" = en carretera, el highway? "la autopista incluye curvas, intercambios y vías de acceso metropolitanas" Natural. "push odometer to 79" = hace que el odómetro marque 79. "Door-to-door from a specific address typically lands within 5–10 miles of that downtown figure." = De puerta a puerta, desde una dirección específica, la distancia suele situarse a 5–10 millas de esa cifra del centro. "within 5–10 miles of" potentially "dentro de un margen de 5 a 10 millas". Better. Heading "Mile by mile on I-35 S" = "Paso a paso por la I-35 S" or "Kilómetro a kilómetro" but units miles. "Milla a milla por la I-35 S". Natural enough. "corridor stacks up cleanly from north to south" = "El recorrido se distribuye de forma clara de norte a sur:" perhaps. "31 miles to San Marcos" = "31 millas hasta San Marcos". "New Braunfels–San Marcos gap" = "tramo entre New Braunfels y San Marcos". "where the clock slips" = donde se pierde tiempo. "traffic and construction routinely cost 10–15 minutes on top of raw distance math" = el tráfico y las obras suelen añadir 10–15 min al cálculo basado solo en la distancia. "Drive-miles snapshot" = "Resumen de las millas en carretera". "Downtown to downtown: 79 road miles, 1 hours 30 minutes in normal traffic." Grammar source weird plural. Translate "De centro a centro: 79 millas en carretera, 1 h 30 min con tráfico normal." Could say "1 hora 30 minutos". Keep entity maybe 5–10. "Add 30–45 minutes..." = "Añade de 30 a 45 minutos..." "Austin or San Antonio rush hours and event weekends." = "si hay hora pico en Austin o San Antonio, o fines de semana con eventos." Heading "Drive miles and times from area towns to San Antonio" = "Millas y tiempos de conducción desde ciudades cercanas hasta San Antonio". "All figures below from same live road-network routing..." = "Todas las cifras siguientes provienen del mismo enrutamiento en tiempo real de la red vial (las distancias son millas en carretera y los tiempos son minutos habituales de conducción con tráfico normal):" Natural. Need "ONLY translated HTML". The hidden marker stripped, but function answer includes marker. No code fence. Need exact tags. Let's formulate. Need maybe "Austin y San Antonio" city names unchanged. I-35 S unchanged. "I-35 S" route code. "New Braunfels" etc unchanged. Potential concern "Keep ALL HTML tags exactly as-is." This means don't alter tags, including ordering. We can maintain exact. Translation entities perhaps preserve. They specifically ask tags, entities okay. Use same entities. Let's ensure no accidental tag modifications. Input:

...

... between ... — about ... via ... If ... (line breaks whitespace okay)

...

... 31 miles to ..., 49 miles, 60 miles ... and 79 miles ... Speed ... 70–75 mph ... New Braunfels–San Marcos ... — ... 10–15 ...

...

... 79 road miles, 1 hours 30 minutes ... Add 30–45 ...

...

...

We can preserve whitespace and tags. Translate "mph" perhaps "mph" unchanged? They didn't say units, but Spanish Latin America often km/h. Yet source says speed limits 70–75 mph. Should we translate unit to "mph" unchanged? Keep phone and URLs only, city names. We can retain mph because exact road info. Could render "límites de velocidad de 70–75 mph". Fine. "Drive miles" maybe title "Millas de carretera de Austin a San Antonio". Natural. "Austin to San Antonio drive miles" likely SEO heading, but natural Spanish. "Distancia en coche de Austin a San Antonio" is more natural but omits miles. "Millas en carretera de Austin a San Antonio" accurate. "between the two downtowns" = "entre los centros de ambas ciudades". In LatAm "centros urbanos". Good. "The drive from Austin to San Antonio is 79 road miles between..." = "El trayecto en coche de Austin a San Antonio son 79 millas en carretera entre los centros urbanos de ambas ciudades — aproximadamente 1 h 30 min..." In Spanish "son 79 millas" natural. "via I-35 S" = "tomando la I-35 S". Better. "If you have ever seen a smaller number quoted" = "Si alguna vez viste que indicaban una cifra menor" maybe "Si has visto..." Neutral. Native LatAm travel copy: "Si alguna vez viste que se citaba una cifra menor..." unnatural. "Si alguna vez viste que te daban una cifra menor..." Natural. "that is straight-line separation" = "se trata de la distancia en línea recta entre las ciudades". "on the ground" = "sobre el terreno" perhaps literal but understood; "en la ruta" better. "en la ruta, la autopista suma curvas, intercambios y vías metropolitanas laterales..." "metro frontage" technically frontage roads. "vías de servicio metropolitanas" perhaps. "y vías de acceso de las zonas metropolitanas" natural. "push odometer to 79" = "hacen que el odómetro marque 79". "Door-to-door from a specific address typically lands within 5–10 miles of that downtown figure." = "De puerta a puerta, desde una dirección específica, la distancia suele estar a 5–10 millas de esa cifra correspondiente al centro." Maybe "dentro de un margen de 5 a 10 millas de esa cifra del centro". Keep –. "within 5–10 miles" ambiguous range; "a 5–10 millas de" direct. "corridor stacks up cleanly" = "El corredor queda ordenado de norte a sur:" maybe "El recorrido se organiza de norte a sur:". "Speed limits are 70–75 mph for most of the run" = "Durante la mayor parte del trayecto, los límites de velocidad son de 70–75 mph". Latin Spanish uses "límite de velocidad" singular? "Los límites de velocidad son de..." okay. "but the two metros and the New Braunfels–San Marcos gap are where clock slips" = "pero los dos núcleos metropolitanos y el tramo New Braunfels–San Marcos son donde se gana tiempo..." Better "donde se pierde tiempo". "el tráfico y las obras en esas zonas suelen añadir de 10–15 minutos al cálculo basado únicamente en la distancia." Good. "Drive-miles snapshot" = "Resumen de las millas en carretera" "Downtown to downtown" = "De centro a centro" perhaps "Del centro al centro". "De centro urbano a

Austin to San Antonio miles: FAQ

More corridor detail: the reverse-direction answer on our How far is Austin from San Antonio? page, the southbound quick-answer on our How far is San Antonio from Austin? page, and full scheduling through our Austin shuttle and San Antonio shuttle city pages.

Driving yourself vs. booking a shuttle

Covering the 79-mile corridor yourself costs about 1 hours 30 minutes behind the wheel each way, plus parking or garage fees at the far end and the same drive home. A reserved shuttle keeps the driver on one direction only and prices as a flat door-to-door total for the whole vehicle — for two or more travelers the math tightens fast, and nobody has to watch I-35 traffic.

FAQ

How many miles is the drive from Austin to San Antonio?

About 79 road miles between the two downtowns via I-35 S. Door-to-door from a specific address typically adds 5-10 miles on either end.

How many miles from San Marcos and New Braunfels to San Antonio?

San Marcos is about 49 miles from downtown San Antonio, New Braunfels about 32 miles, and Seguin about 35 miles, so most of the corridor mileage stacks up north of New Braunfels.

Is it cheaper to drive or take a shuttle from Austin to San Antonio?

Driving solo covers fuel only, but you pay with 3 hours behind the wheel round trip plus parking at the far end. A flat-rate door-to-door shuttle prices the whole vehicle, so two or more travelers often come out close to even without doing the driving.
