Two lanes of I-95 south between exits 7 and 6 have reopened in Stamford Wednesday following a crash.
All lanes were opened just before 5:30 p.m.
The closure led to traffic being backed up to Darien.
State police originally had all lanes of the highway shut down around 3:40 p.m.
The right lane reopened around 4:15 p.m.
There is no word on injuries.
