Cities and school boards are naming streets and buildings after President Obama, breaking with the tradition of waiting until a president is out of office.

• Ludlum Elementary School in Hempstead, N.Y., on Long Island, was renamed after Obama in November. A school in Portland, Ore., is deliberating a similar change.

• Opa-Locka, Fla., renamed one of its main city streets in December. Hollywood, Fla., is considering doing the same.

• St. Louis made an honorary name change to a busy road that used to divide white and black neighborhoods. The postal address is still Delmar Boulevard, but the city will post signs that also designate the street Barack Obama Boulevard.

The tributes are bound to continue, says Indiana University history professor Edward Linenthal.
