Canton Road Corridor
The limits of the Project extend along Canton Road from the northern terminus of the Canton Road Connector north to the Cobb/Cherokee County line.
The project consists of identifying specific safety and operational improvements to Canton Road and key intersections, improved access management for adjacent properties, continuous sidewalks on both sides of the roadway.  This project also includes a raised median between Hembry Drive and Blackwell Square, and other selected locations, based on accident history.

Dallas Highway at Poplar Springs / Holland Road
These improvements are a component of the 2005 1% Special Purpose Local Option Sales Tax (SPLOST) program. The project consists two separate intersection improvements.  Dallas Hwy. at Poplar Springs Rd./Holland Rd. will be realigned and a traffic signal added if warranted.  Second improvement is  a 90 degree realignment with Old Dallas Rd and Holland Rd.

Due West Corridor Improvements
The purpose of this project is to improve the operations and safety of the Due West Road corridor from Old Hamilton Road to Burnt Hickory Road as well as provide bicycle connectivity from Burnt Hickory Road at Acworth Due West Road to Burnt Hickory Road at Due West Road. In addition to the safety and operational improvements, the project will improve traffic flow at the existing intersection of Due West Road/Acworth Due West Road at Due West Road/Kennesaw Due West Road.

Maxham Road Roadway Safety & Operational Improvements
Maxham Road is a 2005 Special Purpose Local Options Sales Tax (SPLOST) program and consists of widening the existing roadway to accommodate 4 -11' lanes with a 20' raised median. U-turn lanes will also be provided at key median breaks. Curb and gutter will be added along the entire length and sidewalk will be introduced along the west side. The alignment will be adjusted to improve any horizontal and vertical curvature deficiencies. The existing bridge over Buttermilk Creek will be widened to accommodate the extra roadway width and sidewalk. The limits of the Maxham Road project are from Old Alabama Road to Veterans Memorial Highway in Cobb County.

Shiloh Road/ Shallowford Road
The purpose of this project is to provide safety and operational improvements to the Shiloh Road/Shallowford Road corridor. The improvements include widening of the existing travel lanes to safe widths, the addition of a center turn lane, additional right turn lanes, and increased capacity at the major intersections. In addition, bike friendly lanes and sidewalk will be included in the project.

Stilesboro Road Thoroughfare and Intersection Improvements
This is a thoroughfare and intersection improvements project in the 2005 Special Purpose Local Options Sales Tax (SPLOST) program.  The Board of Commissioners will be considering the approval of concepts for the Stilesboro Road project at their July 10th meeting.

The proposed improvements will consist of three projects: the widening of the existing 2 and 3 lane corridor between Mars Hill Road and Rose Hedge Way to provide one additional travel lane in each direction; the widening of the existing roadway between Paul Samuel Road and Pine Mountain Road to provide one additional auxillary turn lane in each direction; and the widening of Stilesboro Road from Kennesaw Due West Road to Barrett Parkway to consist of two travel lanes in each direction seperated by a raised grassed median.  Each of these projects will include sidewalk, curb and gutter along both sides of the roadway.

Post Oak Tritt Road
Post Oak Tritt Road is a Roadway Safety & Operational Project in the 2005 SPLOST program. This project is to provide safety enhancements and operational improvements that will provide for better traffic flow on Post Oak Tritt Road.
Project length is approximately 4.05 miles. The limits of the project are from Murdock Road to the Cobb/Fulton County Line. Once completed, the entire project will have continuous sidewalk along the north side of the road.
The project consists of widening the existing travel lanes and shoulders to standard widths, providing turn lanes at key intersections and the addition of curb, gutter, and sidewalk on one side. Horizontal and vertical alignment concerns will be addressed, sections of the roadway will be reconstructed to improve the roadway profile and/or increase the radii of substandard curves. No additional traffic signals are anticipated as part of this project. The existing bridge over Piney Grove Creek will be replaced with a new 2-lane structure with pedestrian sidewalk. The current substandard bridge over Harmony Grove Creek will be replaced with 10' wide x 8' high double box culvert.

West Sandtown Road at Villa Rica Road Roundabout Concept
The limits of the Project include:  West Sandtown Road at Villa Rica Road to the intersection of Villa Rica Road and Irwin Road. Two roundabouts at these intersections are proposed.  The roundabouts will consist of a 115 foot outside diameter circle with a 10 foot outside urban shoulder and 20 foot wide travel lane. 
In addition, a 4 inch high, 10 foot wide truck apron and traversable curb will be on the inside of the travel lane.  Curb and gutter, sidewalk and median landscaping on Villa Rica Road between roundabouts.  Street lights will be installed along the project area.

Windy Hill/ Macland Road Connector
The proposed roadway will connect Windy Hill Road to Macland Road and Powder Springs Road Traffic currently uses several different routes to get to and from Macland Road/Powder Springs Road and Windy Hill Road. Some of these include the use of Callaway Road, Milford Church Road and County Services Parkway, as well as some neighborhood streets as a cut-through. During the morning and evening rush hours these roadways become extremely congested. With traffic volumes expected to increase the traffic congestion during peak periods will continue to be a problem.

In order to alleviate this traffic congestion, a limited access east-west connection from Macland Road/Powder Springs Road to Windy Hill Road has been proposed by Cobb County. Cobb County allocated funds through the Special Purpose Local Option Sales Tax (SPLOST) for the design, right-of-way acquisition and construction of this proposed roadway.

In late October of 2006 a design consultant was contracted by Cobb County to first investigate options to connect Macland Road/Powder Springs Road to Windy Hill Road and to present these options to the public. The goal of the engineering study is to identify one preferred alignment. This is generally defined as one that will be cost effective, minimize impacts to residential and commercial properties, as well as, minimize impacts to environmentally sensitive areas such as wetlands and floodplains.

A project study map has been developed that identifies three alternative alignments. This is strictly a broad brush corridor map and provides a general location for alignments that are being considered.
