Traffic back to normal, sinkhole repaired on I-93 in Concord after 9-plus hours


Interstate 93 in Concord opened Wednesday night at about 10:30 p.m.

The New Hampshire Department of Transportation initially thought the work would be done and the road could re-open around 8, but the repairs took a little longer than expected.

Luckily, no one's car did fall into a giant sinkhole, on I-93 northbound between exits 13 and 14, but there was a close call, however.

A motorcyclist passed over the sinkhole as it collapsed.

While there were no injuries, the sinkhole left thousands with traffic headaches.

"It was fine until we got to about a mile south of Concord," one driver said. "I've been in traffic for an hour, horrible, hot, not a good day for the jeep."

The interstate was shut down for about 9 hours as crews repaired the damaged culvert responsible for the sinkhole.

"It's a very old structure that conveys storm water from the city to the river under the turnpike, so that collapsed," David Smith of the N.H. Department of Transportation said.

Traffic was diverted off of the highway, causing major delays in downtown Concord.

Tuesday's weather could have also been a factor in the collapse.

That part of the interstate got pelted with heavy rain the night before.

The rain "certainly may well have," Smith said. "This isn't something that's happened over one incident like last night's rain storms. It was an old brick, mortar type construction of a culvert and has been there dating back to the mid-50s."
