DARIEN — After being closed for two nearly hours, two lanes of I-95 have reopened after an accident involving two tractor-trailer trucks on Wednesday morning.

The accident, reported around 10:10 a.m., shut down the right and center northbound lanes between exits 12 and 13. The lanes reopened before noon.

State Police said there were no serious injuries in the accident.

Because only one travel lane is open, was nearly five miles of northbound congestion with speeds averaging 10 mph. It took nearly two hours to travel northbound on I-95 between the New York state line and Norwalk.
