By the Mercedes Benz Dome, Northside Drive paved over Davis Street.
Simpson Street has been renamed Joseph E. Boone to the left here, and Ivan Allen Jr. to the right of Northside Drive. There is a gas station on the north west corner, and the area where the stub of Davis St. was left has been bulldozed and turned into a parking lot.
Lets look back in time and a little further south of Simpson.
A good landmark for these old maps is Mitchell Street, which is in the bottom center. At Davis Street, MLK, which goes around the south side of the dome jogs up Northside for a block, and Mitchell still runs west of Northside and east of Elliot.
In this 1903 map section, Vine St. is the left edge of the map and Davis is dead center, on the left edge of the three in the big 83.
Another notable street, that is now under the Dome is Haynes St. It still has a stop sign onto MLK and the street continues south of MLK at the Dome. Today, heading east on MLK/Mitchell at the Dome from Haynes, you also still find Magnum St. where the Hard Rock is located. Then you go under the bridge and you can still take a right turn onto Elliot Street, where there is an Atlanta Fire Station and Elliot Street Deli and Pub.
You can look at Elliot Street and Atlanta Fire Rescue Station 1 here
