6:54 AM: We start with an alert about northbound I-5 – it’s backed up for miles because of a deadly motorcycle crash at Mercer, where three lanes are currently blocked.
7:18 AM: State Patrol has no ETA on how long the I-5 lane closures will continue. Alternate routes are backed up too so anything northbound from here is going to take longer. Meantime, just heard word of a crash on the eastbound West Seattle Bridge by the 99 exit, though it might already have cleared to the shoulder.
7:59 AM: Most of those I-5 lanes have reopened but a long NB backup continues.
