Massachusetts Department of Transportation officials say emergency repairs are currently underway on Interstate 91 in Springfield on the viaduct.
It's in the vicinity of Boland Way and the Memorial Bridge.
Taking a look at the CBS 3 skycam, traffic is already at a significant backup on I-91 in the area and drivers on East Columbus cannot get on the ramp onto I-91 northbound.
The closures are expected to last through the evening commute and drivers are being told to seek an alternate route or face some heavy delays.
