It is already completed. The western terminus is US 64, US 70, and US 79 in Memphis, Tennessee and the eastern terminus is Line Street in Charleston, South Carolina.
I 20 to US 78 in Birmingham. Us 78 is also known as I 22.
I was on it today (4-3-08) and noticed they have opened another section recently. From Industrial Prkwy, in Jasper, to where the new section meets US 78 in Graysville. At that point it dumps you back onto US 78. I may see this thing completed before I die yet. I was on US 78 yesterday (3/20/10), and this portion has now been completed to Coalburg Rd in the Birmingham area about 2.5 miles short of reaching I-65. From that point, it is about 2 miles down to Daniel Payne Dr and then about 0.75 miles to I-65. It greatly improves the trip through Birmingham.
The last interstate highway was completed in 1993 in Los Angeles. The Century Freeway, Interstate 105, was completed after 37 years of construction. The route connects Los Angeles International Airport with Interstates 405, 110, 710, and 605.
It was completed in 1943.
Not all the way yet.... 5 traffic lights on a busy road connect the new highway to the I-20 interchange.
Interstate 70, Interstate 76, Interstate 25, US Highway 50, US Highway 24, US Highway 85, US Highway 87, US Highway 287, US Highway 40, Colorado Route 9... those are some of your major thoroughfares.
To get from Birmingham, AL, to Jasper, AL, you need to be on Interstate 20 East. Get off on the Arkadelphia Road exit (Highway 78). The straightest shot from BHM to Jasper is on highway 78. The QUICKEST way is to take highway 78 from Arkadelphia to Graysville, then get onto Corridor X (future interstate 22) to Jasper.
The first completed section (i.e. open to traffic) was I-70 in Kansas. From the Federal Highway Administration's website: "On Nov. 14, 1956, Gov. Fred Hall participated in a ribbon-cutting to open the newly paved road, and a sign was posted, identifying this section of I-70 as the "first project in the United States completed under the provisions of the new Federal-Aid Highway Act of 1956."
