Be prepared to fight the bridge traffic when traveling across the Merrimack River in Lowell today. If at all possible avoid the Aiken Street Bridge near LeLacheur Park.

Scenes for The Fighter are being filmed today at Top Donut at the corner of Aiken Ave and the VFW Highway. No word if Mark Wahlberg, Christian Bale or Amy Adams are there this morning.

We suggest avoiding the bridge altogether today if you are in a rush. Of course if you want to spot a celebrity...waiting in traffic gives you extra time to rubber neck.

If anyone snaps a pic of any of the celebs send it over.
