From the Annals of the Borders – In 1941, the State of Louisiana lost its legal challenge to the eastern border of Texas. Louisiana claimed that its western boundary extended not to the middle of the Sabine River but to the western bank. The exact boundary has been the subject of much legal wrangling.
From the Annals of Diplomacy – In 1838, the United States and the Republic of Texas signed the Convention of Limits setting out the method for formalizing the disputed boundaries of the fledgling republic. Both parties to the agreement were to appoint surveyors who were to determine a boundary from a point on the Sabine River to the Red River which would form the northeastern limit of Texas. The agreement had the effect of establishing the Red River as the northern boundary and the U.S. recognized Texas claims to disputed territory along the Red River (then named Red River County which comprises the present day Bowie, Red River, Franklin, Titus, Morris, and Cass counties).
Texas Department of Transportation announced that Interstate 10 at the Sabine River has been closed due to high water.
Due to continued flooding from excessive rainfall along the Texas-Louisiana state line, the Texas Department of Transportation has closed Interstate 10 near the state line.
The closure is needed because the Sabine River is cresting above flood stage and dumping water into the low-lying eastbound mainlanes of the interstate near Orange. Louisiana is expected to block westbound traffic as well.
If you are travelling to Louisiana there are not a lot of alternatives. TXDOT is telling drivers leaving Houston to avoid the area entirely by crossing the Sabine on Interstate 20 which would be an approximately 250 mile detour.
From the Annals of Broken Promises – In 1819 the Adams-Onís Treaty was signed by Secretary of State John Quincy Adams for the United States and Luís de Onís for Spain. The treaty fixed the western boundary of the Louisiana Purchase and had the effect of renouncing U.S. claims to Texas. The newly fixed boundary began at the mouth of the Sabine River and ran along its south and west bank to the thirty-second parallel and thence directly north to the Río Roxo (Red River). The boundary then followed the course of the Río Roxo westward to the 100th meridian and then due north to the Arkansas River. From there the boundary followed the southern bank of the Arkansas to its source near the 42nd parallel and then following the 42nd to the “South Sea” (Pacific Ocean). Spain delayed ratification of the treaty and in the interval Mexico declared its independence. The newly formed country refused to accede to the terms of the treaty and never recognized the negotiated boundary.
From the Annals of Neutrality – In 1806, the United States and Spain established the “Neutral Ground” between Louisiana and Texas. After the Louisiana Purchase, the US and Spain had been unable to agree on the boundary between Louisiana and Texas despite Spain having once controlled the area. To avoid an armed clash over the disputed land, Gen. James Wilkinson and Lt. Col. Simón de Herrera, the American and Spanish military commanders, entered into an agreement establishing a Neutral Ground between Texas and Louisiana. Even the boundaries of the NG were never exactly prescribed. The NG was generally described as being bordered by the Arroyo Hondo on the east and the Sabine River on the west. The Gulf of Mexico clearly constituted the Southern boundary and most likely the thirty-second parallel of latitude formed the northern boundary. Despite an agreement that no settlers would be permitted in the NG, settlers from both Spanish and American territory moved in. Predictably, the NG became fertile ground for illegal activity and the US and Spain cooperated in sending joint military expeditions in 1810 and 1812 to enforce order and expel undesirables. The US obtained ownership of the NG with the signing of the Adams-Onis Treaty in 1821.
