Figure 3-9. Peak-Period Congestion on the National Highway System: 2035
Increases in truck and passenger vehicle traffic are forecast to expand recurring, peak- period congestion to 40 percent of the NHS in 2035 compared with 11 percent in 2002. This will slow traffic on nearly 20,000 miles of the NHS and create stop-and-go conditions on an additional 45,000 miles.
