 About midnight last night, Tractor Trailer hit a fire truck that was responding to an earlier accident, 95 southbound in Greenwich, and that has still the road shut down. Greenwich between exits 4 and 3, and the backup starts at exit 7 southbound. Trucks can get off exit 5, take route 1, or if you're a non-commercial vehicle, you can use the parkway. That, so far, is in pretty good shape.
