  Kansas celebrates 50 years of Interstates



325 miles of Interstate was open in the United States. Of that, 105 miles were in Kansas.

Kansas welcomed visiting experts to see the world's largest asphalt project, the surfacing of I-70 through Saline, Lincoln, and Ellsworth counties where asphalt was laid 18 inches thick along 40 miles of dual road. Six asphalt plants turned out 1,650 tons of asphalt and aggregate an hour.

Governor Avery and several beauty queens shared the spotlight with a 101-year-old pioneer woman at the opening of I-70 from Oakley to Colby.

July - I-235 in Wichita was completed.

With the completion of a section of I-70 near Russell, the last section between Colby and St. Louis, Missouri was opened.

Kansas saw its first experimental application of slipform paving on I-35W (now I-135) near McPherson.
