I drove the construction area tonight and found nothing that concerns me for travel tomorrow on I-40 or I-77 North to or from Elkin. There may be a lane closed for paving on I-77 South of I-40 to Troutman exit 45 (US 21/NC 115). This is North of the suggested route to or from Mooresville and should be of no concern unless one chose to take I-40 to I-77 South instead of Old Mountain Road back to Troutman. In the event that this is your plan, I would not anticipate any significant traffic backup on a Saturday night.
I should be available to help tomorrow if needed at 704-929-8456.
