Like a bad love song, the weekend demolition of a bridge made famous by the movies is killing the traffic mood in Los Angeles.

Destruction of the 6th Street Bridge, a supporting player in so many chase scenes down the concrete-covered Los Angeles River, starts Friday night where it crosses U.S. Highway 101, a vital route in and out of downtown that must close to do the work.

The project is further proof that no foreseeable traffic nightmare escapes its own odd branding in Los Angeles.

This one had been dubbed the #101slowjam on Twitter. If all goes well, the 2.5 miles of affected freeway will reopen Sunday, just before the Super Bowl kicks off.

Eventually, the entire 3,500-foot bridge will be replaced by a new roadway that has the potential to become another Hollywood backdrop.
