History

View north at the south end of I-381

The Interstate 381 freeway originally opened to traffic on November 20, 1961, the same time as the part of Interstate 81 that bypasses Bristol to the north.

In its original configuration, the interchange between Interstates 81 and 381 was a single Y interchange, providing access from southbound I-81 to southbound I-381 (via a left exit) and northbound I-381 to northbound I-81. By 1989, ramps were added to make it a full direction T interchange. In 1996, southbound I-81 was moved next to the northbound side, turning the southbound left exit and entrance into right-side ramps.
