The 200 block of Sunset Avenue will become a one-way street beginning Aug. 26, town officials said.
The street will be eastbound only between Bradley Place and North County Road.
Town officials said the change is "a result of new developments along the 200 block of Sunset Avenue and in an effort to ease traffic flow."
One of the busiest corners in Palm Beach, Bradley Place and Sunset Avenue is home to the Publix super market.
Via Flagler, the mixed-use development at the old Testa’s Restaurant site, is being developed along the stretch by the Frisbie Group. The Breakers owns the ground floor, which will contain retail shops; the Frisbie Group will own the second floor and its luxury condominiums.
