Roanoke's Department of Motor Vehicles office will be open throughout the Labor Day holiday weekend to help process a backlog of driver's license applications that accumulated during a state computer failure.

Gov. Bob McDonnell announced that 14 DMVs, including the Roanoke office, will have extended hours on Saturday and will open for half-days on Sunday and Monday.

The additional operating hours will give customers more time to have license or identification card transactions processed. A hardware failure and data storage problem prevented DMV from processing license applications and renewals from Aug. 25 until today.

All DMV offices will be open from 8 a.m. to noon Saturday, and the Roanoke office at 5220 Valleypark Road will remain open until 6 p.m. The Roanoke office also will be open from 1 p.m. to 5 p.m. Sunday, and from 8 a.m. to noon Monday.

McDonnell said DMV will also have extended hours the next weekend, too.

McDonnell also announced that Northrop Grumman -- the private firm that the state contracts for such computer services -- will pay for a postmortem, third-party review of what transpired.

Northrop Grumman released a statement Thursday saying it deeply regrets the disruption and inconvenience the problem caused state agencies and Virginia residents.

"The disruption to the business of state government has ended, but our efforts to examine the factors that contributed to the initial problem and the lengthy restoration of service is just beginning," the statement read. "We support Governor McDonnell's call for an independent review of the incident and we will reimburse the Commonwealth for the reasonable costs of an assessment as it is an essential and responsible measure that will strengthen our ability to protect against future issues."
