It wasn’t a good day for vehicle travel in Suffolk on Friday.

Accidents on major roadways including Nansemond Parkway and U.S. Route 58 kept traffic tied up for hours and sent four people to the hospital.

The first accident, on Nansemond Parkway, involved five vehicles. It occurred about 2 p.m. near Nansemond River High School. Two patients were transported by ambulance to Sentara Belle Harbour for treatment for injuries that were considered non-life-threatening.

Traffic was re-routed through the Nansemond River High School parking lot, but the accident resulted in huge backups on Nansemond Parkway, Bennett’s Pasture Road and other area routes.

Another crash on U.S. Route 58 westbound near the weigh scales happened about 5:30 p.m. and sent two people to the hospital.

That wreck involved a Chesapeake police car. Another vehicle involved in the altercation was overturned, and the two people from the car were taken to the hospital.

The Chesapeake police officer was not injured, city spokeswoman Debbie George said.

Both accidents still are under investigation.
