SEATTLE — Record heat was the likely cause of a buckled road in Seattle's SODO neighborhood. 

Seattle hit a record 95 degrees on Wednesday.  

All northbound lanes of 4th Avenue S. were closed between S. Dawson Street and S. Industrial Way. The road reopened around midnight. 

Southbound traffic was reduced to one lane at S. Industrial Way on Wednesday night. Crews are on scene to determine the structural integrity of the road. 

The incident was reported just after 5:45 p.m. Wednesday.  

SDOT engineers said there were no reports of collisions or injuries as a result of the buckled road. 

After Wednesday's record heat, Thursday will cool down significantly. See the full forecast here.
