"It will encompass milling of the existing surface, repairs as required, overlay of the bridge deck with latex modified concrete and replacement of the expansion joints," Bly said.
She said the work is the final portion of the $23 million construction project to upgrade portions of I-64 and I-77 in Charleston that began earlier this year. The work so far has focused on interstate areas around downtown Charleston.
Crews are replacing the traditional concrete surface with the latex-modified concrete, which is designed to be more durable and less vulnerable to chemical and salt treatments.
While the Eugene A. Carter Memorial Bridge underwent an extensive repainting and overhaul in 2010 and early 2011, Bly said there is more work to be done.
She said with more than 110,000 vehicles crossing it each day, the span is the most highly trafficked bridge in the state, and that leads to a lot of wear and tear.
The bridge's most vulnerable points are around its expansion joints, which allow the structure to expand and contract during hot and cold periods.
"You'll notice with bridges that at the joints connecting it to the road, as it's moving and expanding, then cracks start to develop," Bly said. "It's just that thing is constantly evolving and there are always going to be problems that are going to arise."
The work on the bridge deck is expected to begin next April.
Bly said the work would be done during the overnight hours, just as all other construction work associated with the project has been done this year.
Crews are expected to finish the work by August.
