Crews are building a temporary work bridge that will be used to move equipment, materials and staff to the barge or working platform in Lake Lanier.
"The crane allows vertical supports or piles to be driven into the Lake. This will be the support for the temporary bridge. Crews continue to move equipment and materials to the project area on State Route 284 at Lake Lanier. Working in the Lake preparing to drill for the new concrete support structures or caissons is very specialized. The crews doing that work cannot be in the area until late December. These plans are tentative and are weather dependent," explained Harold Mull, Georgia DOT District Construction Engineer.
This $8.7 million construction project was awarded to E. R. Snell Contractor Inc., of Snellville, Georgia. The project will build a new bridge for SR 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 bike-able shoulder in each direction. The project also builds a new pedestrian tunnel under SR 284. The project completion date is December 31, 2015.
The existing bridge was built in 1958 and does not meet current design standards.
