Emergency crews are working to clear a crash that is tying up traffic along Interstate 95 on Friday afternoon. 

At just before 3 p.m., the Maryland Transportation Authority tweeted that there had been an accident along northbound I-95 just prior to the Mountain Road exit in Harford County. 

The two left lanes are currently shut down. Traffic is getting by to the right, but there are heavy backups heading north on I-95. 

There has been no word on any injuries. 

Motorists should use caution in the area.
