Bridge blast and clean-up captured by local TV news crew.
An overnight implosion took down the Roe Avenue bridge over I-435 on Saturday night, part of a project to replace the brittle span with a new diverging diamond interchange by fall.

A crew of about 40 people spent the rest of the night hauling off the debris.
