The road closed signs that have blocked access to the County Line Road bridges for the past seven weeks are coming down.
"We are on track to complete the repairs and reopen the road by Jan. 1," said Bob Osgood, site communications manager at Exelon's Dresden Generating Station. The company is responsible for maintaining the two bridges that carry traffic over the station's cooling lake.
According to bridge inspection reports on file with the Illinois Department of Transportation (IDOT), both were classified as structurally deficient. The deck and superstructure of both bridges were found to be in poor condition with some advanced deterioration. The 2012 report found some minor problems with the substructure of both bridges, but overall they were in good condition.
Exelon hired D Construction of Coal City to complete the necessary repairs that got underway on Nov. 18.
Crews replaced the bridge deck and installed a weatherproof membrane on the first bridge, located two-tenths of a mile north of Lorenzo Road.
Improvements to the second structure, known as the covered bridge, focused on the replacement of some of the support beams under the bridge deck. A weatherproof membrane was installed and the roadway was resurfaced from Lorenzo Road north to Cottage Road.
Additionally, sections of several columns that support the panels covering the 1,540-foot long bridge were replaced. Crews also repaired or in some cases, replaced panels that were significantly degraded, according to Osgood.
The project cost was estimated at over $1 million.
Located in Wilmington Township, the bridges were constructed with the development of the cooling lake in 1971.
