A truck driver died after his tractor-trailer went off of Interstate 93 in Tilton, New Hampshire and landed in a river early Friday morning.

According to New Hampshire State Police, 48-year-old Benjamin Wilson of Granby, Vermont was driving a tractor-trailer unit on I-93 south and apparently "failed to negotiate a curve in the road" just before 2 a.m.

In a statement, state police said the truck "broke through the center median guardrail, traveled through the median and the embankment, across the railroad tracks, where the tractor-trailer unit came to a final rest on its side in the Winnipesaukee River."

No one else was hurt in the crash, which police said is still under investigation.

One lane of I-93 south was closed as crews worked to pull the truck out of the river.

Anyone who saw the crash or has information about it is asked to email Trooper Conor Davis at Conor.K.Davis@dos.nh.gov.

Tilton, New Hampshire, is about 85 miles north of Boston and more than 60 miles northwest of Portsmouth, New Hampshire. 

The Winnipesaukee River, which is more than 10 miles long, connects Lake Winnipesaukee with the Merrimack River in Franklin and the Pemigewasset River.
