Police said a car trying to make a left turn onto Penobscot Street failed to yield for another car coming across the bridge.
The two cars came together and one was pushed into a pole that holds up a railroad crossing sign and a traffic signal.
Brewer Police Sgt. Paul Gauvin said "There's snow on the ground now so there's ice out on the roads so we want to make sure we are using speeds. Because it says it's a 25 mile an hour speed limit doesn't necessarily mean 25 miles per hour is safe."
One lane of traffic was impacted for a short time.
Police said there is more traffic on the road during the holidays and they're asking everyone to use extra caution.
