Alpharetta city officials said heavy traffic delays will commence downtown on Tuesday, Sept. 8, as part of a project improving a portion of Ga. 9.
City officials said traffic will be reduced to one lane each way from 9 a.m. to 4 p.m. between Marietta Street and Milton Avenue.
Crews will be installing a raised granite median to separate the north and southbound travel lanes. That will require shutting down the inside lanes of the road and shifting traffic to the outer lanes for about a month. All lanes will be open during the morning and afternoon rush hours.
The median is part of a larger project that will result in narrower travel lanes, wider sidewalks and lighting and landscaping improvements. City officials think the upgrade will reduce traffic speeds and make downtown safer.
