NORWALK - Department of Motor Vehicles offices across the state reopened Tuesday after partially closing last week.

The DMV closed down most services in order to perform a major computer upgrade, officials say.

In Norwalk, a long line of customers awaited the reopening.

In Bridgeport, officials had warned residents that wait times would be extra-long for the day. Hundreds showed up anyway, and at one point, customers say the line stretched around the corner.

Tuesday afternoon, the DMV website showed that the average wait time to register a car was five hours, and people who did reach the counter say it seemed as though DMV employees were still working out kinks with the new system.

One woman complained that the computer had lost all traces of her vehicle, and it took four hours to sort out the problem.

But DMV officials say the new system will allow drivers to do more over the Internet, avoiding more lengthy visits to the office in the long term.  Officials say drivers can now renew their registration on the Web and order replacements for damaged license plates.

The DMV says it will need some time to catch up after being closed for a week. The department is granting extensions until Oct. 10 to take care of licenses and registrations that have recently expired.
