paragraph_text: Streets and highways
  
  There are 1,500 miles (2,400 km) of streets, parkways, and avenues in the district. Due to the freeway revolts of the 1960s, much of the proposed interstate highway system through the middle of Washington was never built. Interstate 95 (I-95), the nation's major east coast highway, therefore bends around the district to form the eastern portion of the Capital Beltway. A portion of the proposed highway funding was directed to the region's public transportation infrastructure instead. The interstate highways that continue into Washington, including I-66 and I-395, both terminate shortly after entering the city.
  
  According to a 2010 study, Washington-area commuters spent 70 hours a year in traffic delays, which tied with Chicago for having the nation's worst road congestion. However, 37% of Washington-area commuters take public transportation to work, the second-highest rate in the country. An additional 12% of D.C. commuters walked to work, 6% carpooled, and 3% traveled by bicycle in 2010.
