Colbert, Oklahoma

Colbert's Ferry was an important Red River crossing between Texas and Indian Territory from about 1853 to 1899. Both the Texas Road and the Butterfield Overland Mail route crossed here. It was located on the Texas Road about 3 miles (4.8 km) southeast of present–day Colbert, Bryan County, Oklahoma. The nearest town on the Texas side of the river is Denison. The Missouri, Kansas and Texas Railway (MK&T) built a railroad bridge nearby across the Red River in 1872, which caused Colbert's Ferry to lose a significant amount of traffic. Frank Colbert, the ferry owner, responded by building his own toll bridge, which replaced the ferry. A flood soon washed away both bridges. Meanwhile, he resumed operating the ferry.

With a population of about 50, it was served by a post office in 1873 and 1874.In 1873 the Houston and Texas Central Railway line reached Red River City, where it connected with the Missouri, Kansas and Texas Railroad.

The railway crossed the Red River nearby over the Colbert Bridge, which was also completed in 1873, but destroyed by flooding that same year. The line reopened with the second Colbert Bridge in 1892, but it too was destroyed by flooding in 1908. The route was changed for the third bridge at Carpenters Bluff, which opened in 1910.Red River City subsequently became part of Denison, Texas in Grayson County.
