| | PUBLIC ROADS On-Line (Summer 1996) - Three States Claim First Interstate Highway (Site not responding. Last check: 2007-11-06) |
 | | This seemingly simple question is actually quite complicated, as Missouri, Kansas, and Pennsylvania have staked their claims to the first interstate. |
 | | As soon as that contract was signed, S.W. O'Brien, district engineer for the Bureau of Public Roads, called his headquarters in Washington, D.C., and confirmed that the contract was the first in the nation. |
 | | Considering this fact, perhaps the first interstate highway is really the 260-kilometer stretch of the Pennsylvania Turnpike between Irwin and Carlisle. |
