Police have announced what they are calling significant traffic restrictions and road closures in Cambridge Wednesday for the memorial service for slain MIT Police Officer Sean Collier.

According to the Massachusetts Institute of Technology, the White House has confirmed that Vice President Joe Biden and his wife, Jill, will attend the service, along with Massachusetts Gov. Deval Patrick and other dignitaries.

The memorial service on Briggs Field at noon Wednesday is only for members of law enforcement and the members of the MIT community with valid MIT identification, according to Cambridge Police. As many as 10,000 people are expected to attend, according to MIT.

Cambridge Police said in a press release Tuesday that the road closures for the memorial service will have a major impact on traffic in the city, and they are asking motorists to plan ahead.

Memorial Drive will be closed at midnight Wednesday morning between Massachusetts Avenue and the B.U. Bridge. The Massachusetts Avenue Bridge into Cambridge will also be closed beginning at 7 a.m. Wednesday, April 24.

Massachusetts Avenue will be closed from Albany Street toward Boston beginning at 7 a.m. Wednesday, and Vassar Street will be closed beginning at 6 a.m. between Audrey Street and Massachusetts Avenue.

Authorities say the Boston Marathon bombing suspects shot and killed the 27-year-old Collier in the line of duty last Thursday while he was in his vehicle. Collier’s funeral was being held in Stoneham Tuesday.
