Caisson pouring to close lane of Clarks Bridge Road

POSTED: May 6, 2014 12:06 a.m.

Pouring the ninth of 12 caissons for a new Clarks Bridge will require closure from 9 a.m. to 4 p.m. today of a lane of Clarks Bridge Road.

Delays are expected in the area.

Wednesday, crews will pour the cap for columns poured last week. The cap is the horizontal piece that ties parallel caissons and columns together. A lane closure is required for pouring the cap; one lane will be closed from 9 a.m. to 4 p.m. Wednesday as this work occurs.

Concrete is tested for strength and structure as it arrives to a Georgia DOT project. After concrete is poured, the concrete is tested several times to ensure it cures to the hardness or strength DOT requires for this bridge structure.

This $8.7 million construction project was awarded to E. R. Snell Contractor Inc. of Snellville. The project will build a new bridge for Ga. 284 over the Chattahoochee River portion of Lake Lanier at the Lake Lanier Olympic Center. The new bridge will have 12-feet-wide lanes and an 8-feet-wide bikeable shoulder in each direction. The project also builds a new pedestrian tunnel under Ga. 284. The project completion date is Dec. 31, 2015.

The existing bridge was built in 1958 and does not meet current design standards.
