The left and center lane on I-84 in Farmington were closed following a significant crash on Saturday morning, police said.
State police said only the shoulder is getting by near exit 37 going eastbound.
The crash happened at around 8:30 a.m. and parts are on the westbound side of the roadway, police said.
Police said injuries were reported but could not give any more information.
The lanes have since been reopened.
