RALEIGH — Police and the North Carolina Department of Transportation closed the westbound through lanes of Interstate 440 at Jones Franklin Road for several hours Friday afternoon and evening after the days intense heat caused the roadbed to swell and heave the surface pavement.
NCDOT routed traffic off the interstate via the collector lanes at the interchange and onto U.S. 1 southbound.
Crews were able to make repairs quickly after they got equipment to the scene at about 7 p.m., and the road reopened at 8:15 p.m., NCDOT said.
NCDOT spokesman Steve Abbott said engineers had determined that the 100-plus-degree heat swelled concrete in the base of the road, forcing it up and raising the surface asphalt with it.
Raleigh police had said the bulge in the pavement was high enough that vehicles could lose traction when going over it at high speed, so they closed the road.
No accidents were reported due to the damage or the closure.
