ALBEMARLE COUNTY, Va. (CBS19 NEWS) -- Drivers are being advised to avoid part of Route 29 north due to a sinkhole.

The hole formed around 7:30 a.m. Tuesday in the left lane of the northbound side of the road in the area of Airport Road in northern Albemarle County.
Virginia Department of Transportation crews are there working to figure out what caused the hole to form, dig it out, fill it and fix it.
It has caused the lane to be closed all day while crews excavated to determine the cause of the crumbling roadway.
By 3:30 p.m., VDOT crews had finished digging out the hole, which officials say was likely caused by a void under the road.
A 15-year-old pipe and weather are not the expected causes.
VDOT now needs to fill in the hole and patch the roadway, so drivers can still expect to see traffic delays around the intersection of Route 29 and Airport Road/Profitt Road.
The work is expected to last through Tuesday's drive home, and VDOT suggests drivers take alternate routes home if possible.
The southbound lanes have not been impacted.
