Road improvements underway for three Augusta arteries are progressing on time and mostly on budget, according to state and city transportation officials.
Two Georgia Department of Transportation projects are steadily moving forward, said spokeswoman Cissy McNure.
A project to widen Bobby Jones Expressway and redesign two interchanges is about $2.4 million over budget just more than halfway to completion. An $18.6 million project to widen Wrightsboro Road is less than one-fifth complete.
A city project to widen Marvin Griffin Road, a thoroughfare with heavy industry and truck traffic, began a few months ago, said engineering director Abie Ladson.
Also coming are intersection improvements at Sand Bar Ferry Road and Laney- Walker Boulevard, and traffic signal upgrades on several state routes and Tobacco Road. The improvements, managed by GDOT, include installation of video detection systems that use cameras to monitor traffic counts, speed of vehicles and other measurements.
Bobby Jones Expressway
Interstate 520 is being widened to six lanes, with three lanes in each direction between Gordon Highway and Deans Bridge Road. Both interchanges are being redesigned.
Crews are installing drainage and a sound barrier wall. The exit ramps, traffic lanes and bridge-widening are under construction.
Percent complete: 55 percent
Scheduled completion: June 2014
Original budget: $29.8 million
Current budget: $32.2 million
Between Bobby Jones Expressway and Jimmie Dyess Parkway, the road will be widened from two to four lanes with a 20-foot raised median. The existing road will be realigned between Maddox Drive and Barton Chapel Road to avoid impacting Flowing Wells spring.
At the intersections of Barton Chapel Road and Augusta West Parkway, both roads will be realigned to form one intersection with a traffic signal and left and right turn lanes.
Percent complete: 19 percent
Expected completion: April 2015
Original budget: $18.6 million
Sand Bar Ferry Road and Laney-Walker Boulevard
A video detection system is part of upgrades to the intersection. Grading is underway and new traffic signals are in place.
Percent complete: 63 percent
Expected completion: Nov. 30
Original budget: $726,489
Traffic signal upgrades
Various locations on state routes 121, 223, 288 and Tobacco Road are receiving upgraded traffic signal equipment and video detection systems. Improvements also include enhancements for pedestrians, including accessible sidewalk ramps.
Percent complete: 52 percent
Expected completion: Dec. 31
Original budget: $813,159
Marvin Griffin Road
The road between Mike Padgett Highway and Doug Barnard Parkway will be widened from two to four lanes. Phase one of construction is underway, including clearing rights-of-way and moving utility poles.
Road grading and installing storm water systems will be underway by the end of the year.
Expected completion: 2015
Original budget: $8 million
