Interstate 95 was closed in both directions near Portsmouth, New Hampshire, after a power line fell across the highway around 8 a.m. Thursday.
The highway closed at exit 3 after a broken utility pole resulted in downed wires, according to the New Hampshire Department of Transportation.
It appears that the weight of the snow caused the pole to snap, however thei incident is still under investigation.
NHDOT said I-95 was reopened around 10:30 a.m.
There were no injuries in the incident.
Motorists were urged to seek alternate routes if possible. Traffic was diverted via routes 101, 33, 1 and the Spaulding Turnpike.
