Interstate 40 or I -40 is an Interstate Highway in the US state of Texas. The highway runs through the north of the state, through the so-called “Texas Panhandle”. One passes through the High Plains, and on the way one big city is visited, namely Amarillo. The highway is 285 kilometers long. The entire route coincides with the old Route 66.

Travel directions

The state line at Glenrio.

I-40 near Bushland.

Interstate 40 in New Mexico comes from Albuquerque and crosses the Texas border at Glenrio. I-40 has 2×2 lanes with partial frontage roads. The highway passes through a very sparsely populated area that mainly consists of rangeland. Some remote ranches have direct access to I-40. On the first 100 kilometers to Amarillo there is only one important connection, on the US 385 at Vega. Closer to Amarillo, the area is more cultivated.

The town of Amarillo is reached from the west. Amarillo is the largest city on the I-40 route in Texas and has a full beltway, the Loop 335. I-40 has 2×3 lanes through Amarillo and runs just south of Downtown Amarillo. South of downtown is a rare turbine interchange with I-27, which coincides with US 87 and US 287. East of Amarillo, US 287 branches off as a route to Dallas.

I-40 leads east of Amarillo for another 150 miles through the prairies of the Texas Panhandle. The landscape is mainly flat, with sometimes small differences in height. There are only a few small villages on the route, of which Shamrock is the most important, it also crosses US 83 there. East of Shamrock it follows the border with the state of Oklahoma, then Interstate 40 in Oklahoma continues to Oklahoma City.

History

I-40’s predecessor was the famous US 66, better known as ‘Route 66’. Interstate 40 opened in Texas primarily during the 1960s and early 1970s, and was completed earlier than Interstate 40 in New Mexico, but later than Interstate 40 in Oklahoma. In 1968 the route through Amarillo was completed. A characteristic of western states is that the bypasses around the smaller towns were not completed until later, much activity in these places was dependent on through traffic, so that most bypasses were not opened until the late 1970s and early 1980s. The last section to open was the McLean bypass in 1984.

Texas Interstate 369

Get started	Tenaha
End	Texarkana

Interstate 369 is an Interstate Highway in the US state of Texas. The highway will eventually connect Interstate 69 at Tenaha and Interstate 30 at Little Rock. 6 kilometers of this is the Texarkana bypass. The rest is not yet concrete. The current route via US 59 is approximately 190 kilometers long.

Travel directions

At the village of Tenaha, Interstate 69 from Houston will branch east to Louisiana and I-369 will continue north through East Texas to Texarkana. The route more or less follows US 59 in Texas, via Carthage, Marshall and Atlanta. The I-369 will intersect Interstate 20 in Texas . At Texarkana, I-369 uses the existing bypass, Loop 151.

History

Texarkana’s western bypass opened in the 1980s or 1990s, and in 2011, the connection to I-30 was converted to a half- stack. On September 23, 2013, the number I-369 was signposted on the west ring of Texarkana.

Future

As part of the construction of Interstate 69 in Texas, a branch to Texarkana is also planned, so that Texarkana will be directly connected to Houston. Since the I-69 itself will already bend to the east at Tenaha and therefore will not reach the Texarkana region, the I-369 is planned. On November 16, 2012, the first 6 kilometers around Texarkana were conditionally approved by the AASHTO.

The remainder of I-369 will consist of the construction of an all-new Interstate Highway, and plans for this are still inconclusive in most locations. Most urgent appears to be Marshall’s bypass, which is included in the 2019 Unified Transportation Program for $154 million. A study on the section between Atlanta and Texarkana was completed in October 2018. It recommended that the existing corridor of US 59 be used as much as possible.

At Marshall, a 6-kilometer section of future I-369 as Loop 390 will be constructed between I-20 and US 80.

Traffic intensities

30,000 to 40,000 vehicles use Texarkana’s west ring every day.
