Officially according to the TxDOT web site, I-820 forms three sides of the Fort Worth loop, with I-20 forming the southern edge. The eastern half of I-820 is very old, dating from 1963 to 1965, and is still in its original configuration with only 4 main lanes (2 each way). The northeast section from I-35W to 183/121 is particularly congested. The western half of I-820 is more modern, built mostly in the 1970s and completed in 1982. There have been three major interchange upgrades since the original freeway construction. As of 2007, a plan to rebuild the freeway and add toll lanes, called the Tarrant Express, is being promoted to upgrade the antiquated northeast section.
More history and opening dates for I-820 will be added in the future.
