Work crews have cleared an overturned dump truck and its load of dirt that were blocking several lanes of I-75 Northbound, north of exit 265/North Marietta Parkway, during the first part of Thursday afternoon rush hour.

However, delays remain and traffic speeds along that portion of the interstate heading northbound are still slower than 30 mph, according to Georgia Department of Transportation's website.

Tons of dirt spilled onto the roadway when the dump truck overturned around 3 p.m., according to the Georgia Department of Transportation.
