 Once the northern segments of the loop are completed, I-40 through Winston-Salem would technically complete the beltway loop without the southern section.Construction of the western segment of the beltway was to begin in 1999, but was delayed by a lawsuit aimed at the Environmental Impact Statement.After the legal situation was resolved, the NCDOT then announced construction would begin in 2006; however, in March 2005, the department postponed the start date again until at least 2012, due to budget shortfalls.
