The Capitol Police department is hosting the 28th Annual National Peace Officers’ Memorial Service on Friday, closing off several streets near the Capitol to accommodate the event.

The ceremony, which begins at noon on the West Front, will honor all law enforcement officers who were killed in the line of duty during 2008. Capitol Police spokeswoman Kimberly Schneider said it is expected to end at about 3 p.m.

Until officers determine the “event is clear,— Schneider said these streets will be closed to vehicles:

• First Street Northwest/Southwest between Independence and Constitution avenues

• Pennsylvania Avenue Northwest from First Street Northwest to Third Street Northwest

• Maryland Avenue from First Street Southwest to Third Street Southwest

The event is part of National Police Week and is sponsored by the Grand Lodge Fraternal Order of Police and the Grand Lodge Fraternal Order of Police Auxiliary.
