Construction crews have poured the first of 12 concrete caissons that will support the new Clarks Bridge on Ga. 284/Clarks Bridge Road at Lake Lanier.
The first caisson was drilled Monday to a depth of 103.88 feet when it reached bedrock, and 108 cubic yards of concrete were poured into the 5«-foot diameter steel liner for vertical bridge support, said Harold Mull, Georgia Department of Transportation district construction engineer.
Other work this week includes moving a barge into position so workers can begin drilling for the parallel caisson, Mull said.
The $8.7 million construction project, awarded to E.R. Snell Contractor Inc. of Snellville, calls for construction of the new bridge over the Chattahoochee River arm of Lanier at the Lake Lanier Olympic Center.
The new bridge will have 12-foot lanes and an 8-foot shoulder in each direction.
The project, which also calls for a new pedestrian tunnel under Ga. 284, is set for completion by Dec. 31, 2015.
The existing bridge was built in 1958 and does not meet current design standards.
DOT is shifting traffic in South Hall project
The DOT is shifting traffic this week on Ga. 347/Friendship Road between Interstate 985 and East Jones Road in South Hall.
The shift is being done to allow construction to begin in the original lanes of Ga. 347. East Jones Road runs between Ga. 347 and North Bogan Road, and is west of Friendship Elementary School.
District Engineer Bayne Smith urged drivers to “slow down and use extra caution through the area as motorists get used to these changes.”
The DOT is widening Ga. 347 between Interstate 985 and Ga. 211/Old Winder Highway, an 8-mile project costing $38.4 million.
Work began Oct. 10, 2012, and is expected to be completed by Jan. 12, 2016. A stretch of the new Ga. 347 between Ga. 211 and Spout Springs Road, including new signals, is set to be open to traffic by April 12.
The DOT also is widening Ga. 347/Lanier Islands Parkway between I-985 and McEver Road. The $11.6 million project is set to be finished by Nov. 30.
Open house meeting set for Stone Pile Gap work
The DOT plans to hold an open house meeting 5-7 p.m. Tuesday on plans to improve safety at Stone Pile Gap, or the intersection of Ga. 9/U.S. 19 at Ga. 60 in Lumpkin County.
Engineers and consultants will be available to discuss options, including two roundabout designs and an all-way stop. There won’t be a formal presentation.
Plans call for no impact to the stone pile, district spokeswoman Teri Pope said.
The pile, which, by some accounts, is a Cherokee burial site, “is protected because it is an archaeological, historic and cultural resource,” Pope said.
“Two options (call for moving) the road away from the pile, (and) the third option protects the pile by having it in the center of the roundabout, moving the lanes of traffic farther away than they are now.”
The meeting will take place at the Lumpkin County Community Center, 365 Riley Road, Dahlonega.
After the meeting, plans and handouts can be viewed at the Georgia DOT district office at 2505 Athens Highway in Gainesville.
