All lanes through the Baltimore Harbor Tunnel have been reopened since a burning tire on a car headed northbound earlier in the day led transportation officials to close the thoroughfare.
The Maryland Transportation Authority quickly had reopened the southbound lanes, but for hours had detoured northbound lanes at Childs Street, the last exit for drivers before they enter the tunnel.
Cheryl Sparks, a department spokeswoman, said the tire fire caused a lot of smoke but no injuries.
