The Sandy Springs City Council has approved a $161,100 change order to have an engineering consultant design short-term improvements and explore long-terms solutions to the congested intersection of Abernathy and Roswell roads.
Kimley-Horn & Associates Inc. was awarded a $54,970 contract last October to conduct a roadway safety analysis of the Abernathy-Roswell crossroads area, staff said.
Kimley-Horn will add to that assignment, at a cost of $87,000, designing short-term improvements including right-turn signals for westbound Abernathy; a left-turn barrier and a right-turn lane with mountable curb for southbound Roswell; and a right-in/right-out driveway to the Abernathy Square shopping center.
The consultant also will conduct, for $74,100, a traffic and safety analysis of long-term alternatives, preparing 20-year traffic projections and performing simulations of a number of options.
