A busy overpass on Highway 102 crossing Lacewood Drive wound up with a hole near its centre early Friday morning while some road repair work was taking place.

The damage occurred around 3 a.m. and caused the stretch of road used daily by thousands of commuters to be closed until about 7 a.m.

"A construction crew was removing the centre line barrier ... and it damaged the structure, causing a piece of debris to shake loose," Transportation Department spokesman Brian Taylor said.

He said the overpass was closed termporarily and inspectors were called in. Debris was removed from beneath the overpass and an inspection determined the structure was safe for traffic, he said.

All lanes on Highway 102 were reopened by 7 a.m.

Taylor could not say what other repairs are planned for the overpass.

"But people can rest assured that the structure is safe. We wouldn't let people drive on it if it was unsafe."

There are no other lane closures currently scheduled, he said.

"But certainly we will let everybody know on Twitter if there are any lane closures required for any repairs or further inspection," he said.
