Complete Streets
Howell Mill Road Complete Street Project
Project Location
The Howell Mill Rd. Complete Streets project begins at Marietta St. and ends at Collier Rd. In total the project is approximately 2.25 miles in length.

Existing Conditions
Within this area Howell Mill Rd. is a minor arterial from Marietta St. to I-75 and a major collector street from I-75 to Collier Rd. The section of Howell Mill Rd. from Marietta St. to Huff Rd. is characterized by older buildings that are being redeveloped into trendy restaurants and housing. This section of Howell Mill Rd. includes an urban shoulder with curb and sidewalk and is about 33 ft. wide between Marietta St. and 14th St. and 49 ft. wide between 14th St. and Huff Rd. At the White Provisions Company building the sidewalk narrows and is about 2 ft. in width. The existing unsignalized intersection at Brady Ave. has a driveway that enters very close to the intersection and includes a long pedestrian crossing on the west side of the intersection. The section of Howell Mill Rd. from Huff Rd. to Trabert Ave. is characterized by being surrounded by the Hemphill Water Treatment Facility. Chan-link fence and guardrail run along the majority of Howell Mill Rd. in this area. This section of Howell Mill Rd. includes curb and sidewalk on the west side of the road only, and is about 34 ft. wide. The section of Howell Mill Rd. from Trabert Ave. to Morris St. is characterized by automotive repair shops, landscaping supply businesses and storage facilities. This section of Howell Mill Rd. includes an urban shoulder with curb and sidewalk and is about 47 ft. wide. The section of Howell Mill Rd. from Morris St. to Chattahoochee Ave. transitions from auto repair stores to the Berkeley Park neighborhood. After Chattahoochee Ave. Howell Mill Rd. becomes a very busy corridor with shopping and businesses on both sides. The section of Howell Mill Rd, from Chattahoochee Ave. to Collier Rd., includes an urban shoulder with curb and sidewalk and has a width that varies between 33 ft. and 55 ft. The posted speed limit on Howell Mill Rd. is 35 miles per hour. Signals are present at Marietta St., 8th St., 10th St., 14th St., Huff Rd., 17th St., Chattahoochee Ave., Bellemeade Ave., White St., the Walmart Shopping Complex, I-75, and Collier Rd. The existing pavement within the project limits has a condition rating of poor to very good.

Proposed Improvements
General improvements consist of converting unnecessary curb cuts to sidewalk, fixing crumbling sidewalk and installing new ADA ramps. Landscaping and hardscaping improvements will be made throughout the corridor to increase aesthetics. The existing pavement within the project limits will be replaced with new pavement. In areas where the existing pavement has experienced normal wear and tear and is in need of replacement this will likely be accomplished by removing 2” of existing pavement and replacing it with 2” of new pavement. In areas where the existing pavement is in worse condition this will likely be accomplished by removing 4” to 6” of existing pavement and replacing it with 4” to 6” of new pavement. After the new pavement is placed the roadway will be restriped. It is proposed that from Marietta St. to Brady Avenue the roadway will consist of one travel lane in each direction with a center two way left turn lane. Additionally, it is proposed that Howell Mill be realigned to intersect Marietta Street/West Marietta Street in a more perpendicular fashion.

From Brady Avenue to Morris St. bike lanes will be added to Howell Mill Rd. These bike lanes will be raised bike lanes. To accommodate the bike lanes the roadway will consist of one travel lane in each direction with a center two way left turn lane, except when adjacent to the water treatment facility, in which case there will be no center two way left turn lane. This project will provide linkages to other bike lanes that are proposed along Brady Ave. and Marietta St.

Mid-block crossings will be installed at 9th St. and at 11th St., with rapid flashing beacons to help pedestrians safely cross Howell Mill Rd. At the intersection with Brady Ave. a new signal will be installed, and the pedestrian crossing on the west side of the road will be shortened. A mid-block crossing will be installed between Trabert Ave. and Forrest St. with rapid flashing beacons. From Forrest St. to Antone St. the lane configuration will be updated to consist of one northbound travel lane, one southbound travel lane and a center two-way left turn lane, and shared road markings will be installed in the outside travel lanes. From Antone St. to Collier Rd. the lane configuration will remain unchanged, but shared road markings will be installed in the outside travel lanes. Two mid-block crossing will be installed between Forrest St. and Chattahoochee Ave. with rapid flashing beacons. The intersection with Beck St, will be signalized, and a left turn lane will be added to Howell Mill Rd in the northbound direction. Given the commercial nature of this area and the high amount of traffic it carries, night time construction will be allowed.
