Accident Snarls K/T Muni Line

We received word this morning that a collision, possibly a motorcycle-meets-Muni accident, is blocking the T and K lines near Bayview. 511 has this to say:

On Thursday, June 12th at 8:10am, MUNI reports a collision blocking the K/T line at 3rd and Evans Streets requiring motor coach shuttles between Fourth-King and Third-Evans until further notice.

It seems a motorcycle, according to an SFist reader, allegedly "slid under a diesel truck blocking north bound tracks." The rider's condition? Don't know yet. Will update when we know more.

Thanks, Plug1, for alerting SFist.
