The primary purpose of the meeting, said Public Works Director Michael Smith, was to identify how to improve the safety of the intersection.
“In early 2010, there was a stretch where five, correctable accidents were occurring each month,” Smith said. “At that time, the city put a Band-Aid on the problem by adding a left turn arrow to decrease the accidents until we could get more funding and do more sustainable work.”
Many of the accidents that have occurred at the intersection involve high-angle accidents at accelerated speeds which could potentially cause serious injuries.
Smith said the main problem at the intersection is a sight-distance problem for drivers making a left turn from Spalding Drive onto Chamblee Dunwoody Road.
The department presented three options to correct and improve the intersection:
-Option A involves adding left turn lanes on Spalding Drive and southbound left turns on a green arrow only. The total cost of the project would be about $900,000 but, Smith said, “At first, this option would operate pretty well, but projecting out 20 years, problems would occur and this option doesn’t correct the sight distance problem.”
-Option B includes the improvements made in option A along with raising the grade of the road to correct the sight distance problem. The total cost of the project would be about $1.3 million and would extend into Sandy Springs. “If the cities agree on this option, the thought would be that each city shares in the cost of the project based on which portions of the project extend into Sandy Springs,” Smith said.
-Option C will have the lowest impact on existing roadways, Smith said. It involves changing the current traffic patterns by specifically making Spalding Road a one-way street to the south to eliminate the left turn at the intersection. The total cost would be about $900,000.
The city is seeking input from residents while the public works department takes the next steps to have the project design funded.
