PHILADELPHIA (CBS) — A multi-vehicle accident involving a box truck blocked a portion of Roosevelt Boulevard in the East Falls section of Philadelphia. The accident happened shortly before 11 a.m. on Wednesday.

The right and center lanes of Roosevelt Boulevard southbound at Fox Street are blocked, causing traffic to be backed up.

There is no word on injuries or how the crash happened.

Roosevelt Boulevard is one of the most dangerous roads in America.

Last month, lawmakers authorized a plan to install speed cameras to cut down on crashes.
