In 2001, the company merged with Hemne og Orkladal Billag to create Team Trafikk, that was later sold to Nettbuss.
In 1969, the city council decided to merge the three companies into Trondheim Trafikkselskap, and to organize it as a limited company to limit bureaucratization, and realize efficiency through simpler decision making.
Odd Hovdenak, former director of Trondheim Sporvei, was appointed CEO.

There had been no effictivizations due to the limited company model, and instead ,the new TT would be organized as a municipal agency.
TT established itself at Sorgenfri,after the administration of the former companies had been scattered around town.
The former buses used by Trondheim Sporvei were moved to Sorgenfri, and the disabled transport took over their location at Dalsenget Depot.
