Years in the works, construction of southern leg of NC 540 or the Triangle Expressway begins Monday

Contractors are scheduled to begin work Monday on the new highway interchange south of Garner that will connect Interstate 40 and U.S. 70 with a new, six-lane toll road that will cross southern Wake County.

The new 18-mile segment of the Triangle Expressway, also known as N.C. 540, will run between this 650-acre interchange and N.C. 55 in Apex, extending the toll road that begins at I-40 near Research Triangle Park. The $2.2 billion stretch of highway is expected to open by the end of 2023.
