UPDATE: The accident has cleared and traffic on I-581 and 81 is returning to normal.
PREVIOUS: Major travel headaches at this hour on southbound Interstate 581 between between I-81 and Hershberger Road. There is an accident involving a large dump truck pulling a front loader just south of the Hershberger Road bridge that is blocking all lanes there. As a result, police are diverting all southbound traffic off the highway at Peters Creek Road. 581 is backed up as far as I-81 and local roads in the area are clogged as well. And in the last half hour, police are now blocking access to 581 from 81, and there are growing delays in both directions as you head south from Hollins or north from Electric Road.
