Some rolling road closures are possible today as dignitaries in town for former president Ronald Reagan's funeral come and go. But authorities were not predicting any major traffic disruptions such as those experienced Wednesday and at midday those predictions were holding throughout the city.

Visitors to the Capitol, where Reagan lies in state, may need protection from the rain later, however. The National Weather Service says there is a 60 percent chance of thunderstorms starting after 4 p.m. today and continuing through the night and into Friday, when the ceremonies shift to the Washington National Cathedral.

On Friday, however, some parts of the city will have major roads closed for the funeral procession from the Capitol to the Washington National Cathedral in the morning and then again from the cathedral to Andrews Air Force Base in Suitland after the services.

City officials said today that preliminary plans call for the hearse and accompanying cars to travel from the Capitol sometime between 10:30 and 10:45 a.m. west on Constitution Avenue, south on Third Street NW, west on Independence Avenue, north on 17th Street, west on Pennsylvania Avenue, north on 22nd Street, west on Massachusetts Avenue, then north on Wisconsin Avenue to the cathedral. Those streets will be closed to all traffic beginning as early as 10 a.m. and will reopen once the procession passes.

When the hearse and the Reagan family leave the cathedral to return to California, they will travel south on Wisconsin Avenue, east on Massachusetts Avenue, south on Waterside Drive and merge onto Rock Creek Parkway; east on Independence Avenue, SW; south on Maine Avenue, SW; east on the SE/SW Freeway; south on Route 295, and south on Suitland Parkway to Suitland Road and the main gate of Andrews Air Force Base.

Traffic restrictions--except for residents of the neighborhood--will also be in place starting at 9 a.m. for Macomb Street, Massachusetts Avenue, 34th Street and Idaho Avenue adjoining the cathedral and will remain until the hearse leaves the cathedral.

In addition, motorcades bringing other dignitaries to the service could disrupt traffic on other streets.

Tonight, Metro officials said free shuttle service again will be provided from the Stadium-Armory Metrorail station -- at Lot 3 of Robert F. Kennedy Memorial Stadium at 19th and East Capitol Streets NE -- to near the Capitol from 11:30 p.m. to 6 a.m. for people who want to view Reagan's casket in the Capitol Rotunda.

Shuttle bus riders will be dropped off at 7th Street and Madison Drive on the Mall. Those returning to RFK will be picked up at First Street and Constitution Avenue NE.
