ARPANET stands for Advanced Research Projects Agency Network. ARPA created it during the time of cold war. It was the first packet switching network and was also known as the 'Predecessor of the Global internet'.
Packet Switching has become the leading foundation for both voice and data communication worldwide. Prior to this, data communication was based on circuit switching. A System could use one communication link to communicate with another machine with packet switching.
The ARPANET project began with its seed ideas, as early as 1962. From the page below, you can read: "First ARPANET IMP log: the first message ever sent via the ARPANET, 10:30 pm, 29 October 1969." The direct answer to your question, then, is sometime between 1962 and October 29, 1969, depending on your definition of 'constructed'.

ARPAnet eventually developed into the World Wide Web.
ARPANET (Advanced Research Projects Agency Network) was an early packet switching network that became the technical foundation of the Internet.
The Internet as we know it today is based on Arpanet.
ARPANET was original name of the computer network that eventually morphed into the Internet.
The Internet started as Arpanet; today it is called the Internet.The Internet started as Arpanet; today it is called the Internet.The Internet started as Arpanet; today it is called the Internet.The Internet started as Arpanet; today it is called the Internet.
The Internet is the system of communication that developed from ARPANET. The internet is its civilian counterpart.
Arpanet stands for Advance Research Project AgencyNETwork. It was funded by the US Advance Research Project Agency (ARPA). Arpanet was launched in 1969 in four sites including two University of California campuses, the Stanford Research Institute, and the University of Utah.
