Route 20, the Bradley Connector, is closed in both directions because of a gas leak in East Granby.
The gas leak is on Larch Drive in East Granby, according to the First Selectman's office. Officials from Yankee Gas said a contractor hit a line.
The First Selectman's office said this is not a very residential area. Whether there will be evacuations is not known.
Airport officials said they do not believe this is having an impact on the airport.
No additional information was immediately available.
