The MTA began rerouting the B54 bus Monday.
Eastbound bus stops on Myrtle Avenue at Steuben Street and Washington Avenue have been temporarily relocated to make room for construction at Myrtle Plaza from Emerson Place to Hall Street.
The new temporary bus stops will be near the intersections of Washington and Myrtle avenues and Classon and Willoughby avenues.
The MTA says the B54 will use the changed route until July.
Westbound buses are not affected.
