Interstate 84 in Waterbury was reopened Thursday afternoon after being briefly closed for police activity, state police said.
The Department of Transportation said it happened on the westbound side between exits 19 and 18.
State police said they pursued a man they said was "despondent." The pursuit started near exit 30 of Route 8 and ended on I-84.
They said they were able to take him into custody and send him to the hospital in an ambulance.
State police Lt. J. Paul Vance called the incident a medical call and would not release any other information.
The highway was cleared a short time later.
