A truck driver trailing behind the vehicle that caused the accident captured the crash on a dash cam.
In it you see the cargo on the trailer hit the sign and then the overpass. The sign is brought down and then the construction equipment is pulled off the trailer by the impact with the overpass.
The driver who took the video is then seen stopping on the fallen sign and then backing up.
MDOT says eastbound I-96 will remain closed overnight and into tomorrow. Officials say traffic can get by on the median, but because of the backups the accident has caused, the freeway should be considered closed.
Drivers are advised to find an alternate route for rush hour.
Engineers brought in to examine the Pleasant Valley overpass have determined that they will need to demolish the 1/2 of the bridge that has been damaged. They hope to have bids out sometime Thursday, with demolition also beginning then.
MDOT says they hope to have the freeway reopened later in the day Thursday, but they are not yet sure how the work will affect the evening rush hour.
