The Baytown Tunnel or Baytown – La Porte Tunnel was a two-lane underwater motor-vehicle tunnel connecting Baytown and La Porte, two suburbs of Houston, Texas. Completed in 1953, it traveled northeast-southwest underneath the Houston Ship Channel and had a length of 4,110 feet (1,250 m). It was closed to vehicular traffic in 1995 with the opening of the Fred Hartman Bridge, and subsequently demolished beginning in 1997 in order for the U.S. Army Corps of Engineers to deepen the channel in 1998.The Fred Hartman Bridge had been designed to replace the Baytown Tunnel (of depth clearance 40 feet (12.2 m)), which had to be removed when the Houston Ship Channel was deepened to 45 feet (13.7 m), with a minimum 530 feet (161.5 m) bottom width, to accommodate larger ships. The last section of the Baytown Tunnel was removed on September 14, 1999, with removal of the tunnel being the responsibility of the Texas Department of Transportation.

La Porte, Texas

La Porte ( lə PORT) is a city in Harris County, Texas, United States, within the Bay Area of the Houston–Sugar Land–Baytown metropolitan area. As of the 2020 census, the city population was 35,124. La Porte is the fourth-largest incorporated city in Harris County. When La Porte celebrated its centennial in 1992, it was the home of Barbours Cut Terminal, operated by the Port of Houston Authority since 1977. Fifteen years later, the Port of Houston's newest addition, Bayport Terminal, was established just south of La Porte. The area around La Porte has served an increasingly important role in international trade since the 1970s. The area around modern La Porte gained fame early in Texas history as the location of the Battle of San Jacinto on April 21, 1836, which ended the Texas Revolution, establishing the independence of the Republic of Texas from Mexico. The San Jacinto Monument, in the unincorporated area of La Porte, commemorates the battle. During the early 20th century, particularly the 1920s and 1930s, La Porte's Sylvan Beach became a nationally known tourist destination attracting some of the nation's most well-known entertainers. As a result of changing economics in the Houston area and beach erosion, the tourist business declined while industrial development in the area grew. During World War II and afterward, La Porte's economy rapidly shifted toward petroleum/petrochemicals and shipping, which developed as the dominant industries in the Pasadena-Baytown area.
