The Springfield Interchange is in Fairfax County, Virginia, 10 miles from Washington, D.C. A daily average of about 430,000 vehicles pass through the Springfield Interchange, where I-95, I-395 and I-495 come together. To improve traffic flow, the Virginia Department of Transportation rebuilt the interchange to make it safer for commuters and long-distance travelers. This improvement project took 8 years to complete. The project consisted of building more than 50 bridges and widening I-95 to 24 lanes between the Beltway and Franconia Road.
