The Seattle Police Department this morning released additional details on Friday's procession and memorial for Officer Timothy Brenton, who was killed Saturday night. Here's the SPD's news release:

A memorial procession along city streets for Seattle Police Officer Timothy Brenton will be held on Friday, November 6. Approximately 1,000 to 1,500 vehicles will depart at 9 a.m. from the University of Washington and will travel to a service for the slain officer at Key Arena.

During the procession, which is expected to last from 9 a.m. to noon, other traffic will not be allowed on the route and will not be allowed to cross it. The Seattle Department of Transportation (SDOT) advises travelers to expect severe congestion near its path, especially as mourners are also anticipated along its course.

The memorial procession will use the following route: begins at the University of Washington's E-1 parking lot; south on Montlake Blvd NE to 24th Ave E; south on 24th to 23rd Ave E; south on 23rd to E Madison St; west on Madison to E Pine St; west on Pine to Broadway; north on Broadway to E Denny Way; west on Denny to 1st Ave N; north on 1st to Key Arena. Staging will begin in the E-1 parking lot (north of Husky Stadium on Montlake Blvd NE) beginning at approximately 8 a.m.

Parking will not be allowed along the route and temporary "No Parking" signs will be emplaced. Officers from the Seattle Police Department will manage all intersections for the procession. 1st Avenue N (Denny to Mercer) and Mercer Street (1st to 5th avenues N) will be closed when the procession arrives at those locations. Roads around the Seattle Center will also be closed to traffic, to include parking, prior to the event.

The public memorial service at Key Arena will begin at 1 p.m., with doors opening at 11 a.m. No formal procession is planned after the ceremony. All questions concerning the procession route and traffic impacts should be directed to the Seattle Department of Transportation.
