The span that collapsed was ~1200 feet..

spans; beginning on the south side and continuing for several spans to the north. A span is a section supported by pillars. At least 4 went down.
Looks like the span is somewhere around 2000 feet on Apple map. You can see the shadow of the span if you zoom in. Add a couple of other road sections and maybe 2500 feet? I was just reporting what a talking head said early this morning..
