Travel directions

The SH 80 in San Marcos.

SH 80 begins in Karnes City, a small town 80 kilometers southeast of San Antonio. From Karnes City to San Marcos, traffic has two options, the western route via SH 123, passing through Seguin, or the slightly longer SH 80, passing through Luling. The first section of SH 80 to Luling passes through flat prairie land, actually part of the Coastal Bend, the coastal plain of the Gulf of Mexico, although SH 80 already runs quite far inland here. The road leads through only small villages. Just before Luling you cross Interstate 10, after which the road bends slightly to the northwest. The second half of the route from Luling to San Marcos is a four-lane road. At the city of San Marcos, SH 80 ends at Interstate 35.


SH 80 was added to the planned network of state highways in Texas in 1926, as a north-south route from Luling to San Marcos. In 1928, the route was extended northwest from San Marcos to the Texas Hill Country hamlet of Wimberley. In 1940 the route was extended south from Luling to Karnes City on a newly constructed road, but SH 80 was also shortened from Wimberley back to San Marcos in 1942.

In 2005, the intersection with SH 21 just outside San Marcos was made grade separated with an overpass for SH 80.

Traffic intensities

Every day, 3,300 to 4,700 vehicles run between Karnes City and Luling and 8,000 vehicles between Luling and San Marcos.

State Route 81, commonly known as State Highway 81 or SH 81 is a state route in the U.S. state of Texas, located in the North Texas region. SH 81 forms a north-south route between Hillsboro and Grandview, south of Fort Worth. It concerns the former route of the US 81. SH 81 is 38 kilometers long.

Travel directions

SH 81 begins south of Hillsboro at a junction with Interstate 35. The first section from there to Hillsboro is a 2×2 divided highway. The road then leads through downtown Hillsboro. The town is best known as the place where I-35 splits into I-35E and I-35W. SH 81 then parallels I-35W. The road leads through prairie country and passes through the villages of Itasca and Grandview, before SH 81 terminates at Interstate 35W, 31 miles south of Fort Worth.


The original SH 81 was added to the network of planned state highways in Texas in 1926, as a north-south route from Cuero via San Antonio to Bandera in South Texas. The route was extended to Kerrville in 1928 and to De Leon in 1933, continuing north. In 1936, the section southeast of San Antonio was renumbered SH 27 and in 1938 the section between San Antonio and Kerrville was renumbered SH 16, after which the entire SH 81 was scrapped in 1939 in favor of SH 16.

SH 81’s current route between Hillsboro and Grandview was originally part of US 81, which had through importance before I-35W was built. The entire US 81 was scrapped in 1991 between Laredo and Fort Worth, after which the section between Hillsboro and Grandview was renumbered as SH 81.

Port Arthur

State Route 82, commonly known as State Highway 82 or SH 82 is a state route in the US state of Texas. The road makes a short connection in the extreme southeast of the state, from the Louisiana border to Port Arthur. SH 82 is 21 kilometers long.

Travel directions

The border with Louisiana is formed by the Sabine River, which here is more of a bay than a river. The two-lane Sabine Lake Causeway Bridge crosses the river, after which SH 82 crosses a narrow spit of land between the river and an oil industry canal. Just before Port Arthur, the canal is crossed via a cantilever truss bridge. SH 82 then runs between the oil refineries in Port Arthur and ends at a junction with SH 73.


SH 82 was originally assigned in 1926 to a route from Fort Stockton to Monahans in West Texas. In 1928 the route was extended north from Monahans to Kermit and in 1933 to the New Mexico border. In 1958 the road was renumbered as SH 18.

In 1975 the number was reassigned, to the current route south of Port Arthur. The bridge over the Sabine River was constructed as a swing bridge between 1957 and 1958. The bridge was damaged by Hurricane Rita in 2005, but was repaired. The bridge was later replaced by a high fixed bridge between 2008 and 2010. In 1970, the Martin Luther King Bridge opened over the Gulf Intracoastal Waterway in Port Arthur. This is a large steel cantilever truss bridge.

Traffic intensities

Every day, 1,900 vehicles cross the Lake Sabine Causeway Bridge and 1,000 vehicles cross the Martin Luther King Bridge. This rises to 7,800 vehicles in Port Arthur off SH 73.
