Alt Text Map of San Antonio Missions National Historical Park in Texas. The San Antonio River, shown in blue, and the Mission Trail connect four missions labeled with green callout boxes and green park areas. These and other sites make a loose, almost vertical line down the map. Streets are shown in white against a tan background. Extended Description At the northernmost tip of the map is a grid of streets around The Alamo and River Walk, which is shaded in gray and bordered in blue. From the top down, east-west streets are Travis Street, Houston Street, Commerce Street, Dolorosa Street, which becomes Market Street, and César Chávez Boulevard farther south. The joint Interstates 10 and 35 run up the left side of the map and Interstate 37, also labeled US Route 281, runs along the right side. Other north-south streets from left to right include South Flores Street, St Mary’s Street, Navarro Street, Losoya Street, which becomes Broadway, and Alamo Street, which becomes North Alamo Street. The Alamo is near the corner of Alamo and Houston streets. Other sites marked in gray are El Mercado between Dolorosa and Commerce streets to the west and San Fernando Cathedral near South Flores and Dolorosa streets. The pale green Hemisfair Park stretches between Market Street and César Chávez Boulevard and from Alamo Street to Interstate 37. The Convention Center, Tower of the Americas, and Institute of Texan Cultures are in the park, and the Alamodome is across the interstate between exits 141A and 140. A yellow line encased in green representing the Mission Trail begins on Alamo Street at The Alamo. It continues south through town and veers onto South St Mary’s Street. A red dashed line representing the River Walk Trail begins a few blocks north of César Chávez Boulevard on the San Antonio River. It winds along the river down the length of the map. Continuing south is King William Historic District and Southtown, which are hemmed by the San Antonio river to the west, César Chávez Boulevard to the north, South St Mary’s Street to the east, and Eagleland Drive to the south. Lone Star Boulevard runs east-west south of Southtown and leads to Roosevelt Park, shown in pale green. The Mission Trail continues onto Mission Road south of this, and the Mission and River Walk trails both cross Interstate 10, which is also labeled US Route 90, that travels east-west across this area. The river walk winds past pale green Confluence Park and Concepción Park, which has a picnic area. The Mission Trail continues past Mission Conceptión, which is on Mission Road between Theo Parkway and East Theo Avenue. Farther south are the Approximate site of Mission San Francisco Xavier Nájera and Park Headquarters. Now about a third of the way down the map, the Mission Trail and River Walk Trail switch places and the River Walks Trail and river continue to Mission Park, shaded dark green, and Padre Park, which has a picnic area and San Juan Dam (no access). The Mission Trail continues past Mission San José, a Visitor Center, and picnic area as it branches onto Napier Avenue and then Riverfront Parkway. A yellow line encased with a double dashed green line continues south on Roosevelt Avenue, turns east on March Avenue, and south again on Mission Road before rejoining the main route. Green text here reads “detour when Mission Trail is closed by high water.” The main Mission Trail and River Walk Trail come together at the intersection of Napier Avenue and Riverfront Parkway. A note in red text where they cross SE Military Drive, also labeled Loop 13, reads, “Caution: Low overpass, 10ft 10in (3.3 meters) clearance.” The trails continue south past Estrada Park, which has a picnic area, New Estrada Dam, and Estrada Dam. Red text in this area reads, “Warning: Use caution when water flows over road.” The trails travel by Acequia Park, which has a picnic area, and into an area marked in white and labeled Acequia de Espada. This white area encompasses the remaining legs of both the Mission Trail and River Walk Trail, and sites within it include Mission San Juan, Spanish Colonial Farm, Nature Trail, Espada Aqueduct, historic Piedras Creek, Camino Coahuilteca, and Mission Espada. The Mission Trail creates a loop, traveling south along Villamain Road and curving up and west to Espada Road, which meets with Mission Road near the detour route. Red text near Camino Coahuilteca reads, “Warning: Use caution when water flows over road.” Interstate 410, also marked US Route 281, travels east-west across this lower leg of the park system as one-way frontage roads. South Presa Street runs the length of the map near, along, or through eastern park borders. A green note near the road reads, “23 miles (37 kilometers) from Visitor Center to Rancho de las Cabras via South Presa Street and US Route 181.” South Presa Street peels east near the bottom right corner of the map. Green text near an arrow pointing off the right edge reads, “To Rancho de las Cabras (limited access).” Legend In the lower right corner of the map, the legend reads as follows: Dark green for National Park Service land, Light green for Other public park and protected land, Yellow line encased in green for Mission Trail driving tour (see map for detour when Mission Trail is closed by high water in river), Red dashed line for River Walk trail, Gray dashed line for Other trail, Blue line encased in lighter blue for Acequia (historic irrigation system) still in use within the park boundary, used today for irrigation, and A symbol for Picnic area. Text in the legend reads, “The Mission Trail: This driving tour connects the missions. Get directions from park staff or look for the distinctive signs along city streets.” A scale below the legend measures distances of 0.5 and 1 kilometers and 0.5 and 1 miles.
