During this time, one of the first loop roads in the nation (Loop 304) was built around the city. This traffic reliever was procured through the works of heavyweight politicians who called Crockett home. Blues singer Lightnin' Hopkins was once arrested in Crockett. In recent years, the economy of Crockett has expanded with the construction of new retail space on Loop 304. Several historic buildings in downtown have been renovated to accommodate new office and service space. Renewed interest in reserves of natural gas in the surrounding area has led to construction of energy infrastructure and receipt of royalty revenues for land.
