The first construction contract was let for SIU 7 on October 30, 2009, covering Section 4 (middle leg of the Union City Bypass). The winning bid for constructing the section between TN-21 and TN-5 northwest of Union City, was awarded to Ford Construction Company of Dyersburg for $33 million. Construction on this section of the Union City Bypass began in the Spring of 2010, and was completed in the summer of 2012. However, it will remain closed to traffic until adjacent sections are completed. As of July 2014, land acquisition and utility relocations were underway in all five sections from Troy to Union City. TDOT awarded a construction contract for 2.4 mile Section 3 (southern leg of the Union City Bypass) in March 2016, and planned to let a second contract for Section 5 (northern leg of the Union City Bypass) in December 2016. Work began on Section 3 in June 2016.
