The latest in the legal battle over artist Christo's efforts to drape the Arkansas River with fabric (all times local):

8:20 a.m.

Residents fighting the artist Christo's dream of draping the Arkansas River with fabric are headed to court again to try to block the project first proposed nearly 20 years ago.

Judges at the 10th Circuit Court of Appeals in Denver are set to hear arguments Wednesday morning about whether federal approval of the Over the River project should be thrown out.

It's the last pending legal challenge to the work.

Last month, Colorado's Supreme Court refused to reconsider state approval for the project, which would involve draping 6 feet of translucent fabric panels over a 42-mile stretch of the river between Salida and Canon City. It would take two years to install and be on display for two weeks.

A ruling isn't expected immediately.
