Gainesville, Ga. – Georgia DOT announces a concrete pour is scheduled for Wednesday, November 5 to begin tying together the “pieces” and make the new State Route 284 Bridge one structure at the Lake Lanier Olympic Center, if weather cooperates.
“The new bridge will carry traffic over Lake Lanier. It has seven spans. The contractor plans to pour two spans Wednesday. The northbound lane will be closed from 9 a.m. to 4 p.m. as the concrete pour occurs. We want you to know about the work and the lane closure because traffic will be impacted,” explained Harold Mull, Georgia DOT District Construction Engineer.
The “pieces” of the bridge include vertical concrete columns, horizontal concrete caps that form a capital T shape on the vertical columns. Then the horizontal bridge beams stretch between the caps. Steel plates are welded into place between the beams then concrete is poured into the steel pans tying the entire structure together. This concrete forms the driving surface of the bridge.
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 eight 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.
