Instead of taking I-40 west to Interstate 85, drivers can take N.C. 147 through Durham and then I-85 back down to I-40.
The DOT and the state Highway Patrol say the route is safer.
WRAL drove the route during the afternoon rush hour and found it saved a minute of drive time.
The DOT will consider making that route a mandatory detour for trucks until the construction project is finished.
At 8 p.m. Friday, the DOT is closing the Highway 147 ramp from I-40 westbound for repaving.
It will reopen Monday at 6 a.m.
