A driver was trapped in his car on I-95 North in Walpole just before rush hour.
The crash caused more than an hour of backups on route 95. A medical helicopter was flown in to rush the 24-year-old New Hampshire man to the hospital. The one car crash happened just north of exit 10.
Police say the driver struck the guardrail underneath the overpass. He was transported in with serious injuries but was not listed in critical condition.
