Sandy Springs city officials plan a public open house next month on pending road improvements in the Johnson Ferry Road/Mount Vernon Highway corridor.

City officials plan to install two roundabouts to relieve bottlenecks. One will be west of the Johnson Ferry Road, Mount Vernon Highway and Boylston Drive intersection, with the other at Johnson Ferry, Mount Vernon and the Mount Vernon Towers driveway.

Sandy Springs officials will have plans at the ready and will answer questions during the informal event 6-8 p.m. April 2 at the Sandy Springs City Hall council chambers, 7840 Roswell Road, Building 500.
