The new road will extend three miles from Georgia Highway 92 and tie in to an existing section of Cleburne Parkway which intersects with U.S. Highway 278 near the Cobb County line. The idea is to reduce traffic congestion by providing an alternate route to either U.S. 278 or local streets to bypass Hiram.
Greene said crews working for the county’s contractor, G.P. Enterprises, have just begun hauling dirt to the largest fill area at the Norfolk Southern railroad overpass near the north end of the project.
The contractor hired a bridge subcontractor, Gregory Bridge Co., to build the overpass. The bridge columns are up, and the contractor is now building the ramps for the bridge, Greene said.
“That’s the last major structure that needs to go in,” said Greene. “Getting past that railroad.”
The completion date in the contract with G.P. Enterprises is July 29, 2013.
“We’re just past the halfway point,” said Greene.
On the other end of the project near Georgia Highway 92 and Bill Carruth Parkway, work is wrapping up on the bridge over Mill Creek.
The concrete deck of the largest of the three bridges in the project, which will also be the longest bridge in the county, was just finished, according to Greene.
Greene said the widening of Cleburne Parkway would be the most difficult part of the project from here on because of dealing with traffic and utilities on an existing road.
“The more difficult work along Cleburne will linger toward the end,” said Greene. “Most of the paving through the project will be completed by this fall. It’s going to look like a lot of it is finished except for the intersections and last half mile along Cleburne by the fall.”
The project began in February 2011 and the DOT has $16.3 million available for the project. The contract awarded is for $15.1 million, but the department has allotted extra money for fuel costs and potential overruns.
The project is being funded through federal and state grants, according to Greene. The funding for the project was provided through an agreement with the Georgia Regional Transportation Authority, the State Road and Toll Authority and Georgia DOT.
GRTA agreed to sponsor the roadway project in return for the county providing start-up funds for the Xpress bus service in 2003.
East Hiram Parkway got the go-ahead for construction seven years later, in 2010.
