A portion of Route 2 westbound is closed in Hartford, according to transportation officials.
As of 7:30 a.m. on Wednesday, only the left lane was getting by.
However, state police said they expected to close the whole highway down to clean up an oil spot.
The reason is a multi-vehicle crash.
No one was hurt. A cause remains under investigation.
