Gwinnett commissioners approved construction contracts for two SPLOST- and grant-funded transportation upgrades at their regular meeting this past week, including some in the Grayson area.
The intersection of Webb Gin House Road and Bennett Road will get a traffic light and left turn lanes over the summer. The same safety improvement contract will add a deceleration lane with a right turn lane along Grayson Parkway/State Route 84 at the intersection with Pinehurst Road.
The work also includes curb and gutter and extending the existing sidewalks along Grayson Parkway. CMES, Inc. was the lowest of seven bidders for the two projects at $579,847.50. These improvements are being funding by the 2009 sales tax program.
Jimmy Carter Improvements
Upgrades to Jimmy Carter Boulevard at Singleton Road will give a boost to pedestrian safety. The project will add turn lanes on three legs of the intersection along with improvements to sidewalks, curb and gutter, and retaining walls. CMES, Inc. was the lowest of four bidders at $918,964.10.
Less than 8 percent of the cost comes from local SPLOST funds while the Georgia Department of Transportation will pay 43 percent and the State Road and Tollway Authority will contribute almost 49 percent.
Gwinnett’s first diverging diamond intersection won commission approval for construction to begin this summer on Pleasant Hill Road at I-85.
The design uses the existing bridge more efficiently by switching traffic to the left to allow smooth left turns onto the interstate. Pedestrians will use a new walkway in the median.
, of Snellville was the lowest of three bidders at just under $4.3 million, which will come from SPLOST funds. The work involves widening a half-mile of roadway plus new retaining walls, curb and gutter, sidewalks and traffic signals. The timing of other signals approaching the intersection will also get adjustments to ensure smooth traffic flow.
Gwinnett Transportation Director Kim Conroy said, “The Gwinnett Place Community Improvement District has worked closely with our traffic engineers on the new design, which is similar to the diverging diamond that opened recently on Ashford-Dunwoody Road at I-285 near Perimeter Mall. We estimate this will extend the useful life of the existing bridge by about 10 years with no widening needed.”
The project is expected to be complete within a year.
