Williams' truck went off the left side of the road for more than 200 feet before hitting the guardrail and slamming into a bridge support at Exit-348. That's about 20 miles southeast of I-95.
The trucker was pronounced dead at the scene.
Westbound traffic was flowing again by mid-morning, but the bridge will have to be inspected before eastbound traffic will be allowed to pass under it again. It will likely be mid-afternoon before the highway completely opens up.
In the meantime, traffic is being diverted through a detour.
