Final paving for the County Line Road widening, a project that started more than a year ago, is planned to begin Wednesday with traffic congestion expected.
The city of Kettering announced Tuesday on its website the $2.6 million investment it is partnering on with Beavercreek to expand access and jobs to Miami Valley Research Park is reaching its final stages.
Milling and paving work will last about 10 days, depending on weather, officials said.
County Line’s expansion includes widening the number of lanes from three to five from Vale Drive to Dorothy Lane, improving access to Interstate 675.
Contractor R.B. Jergens’ tentative schedule, according to Kettering, includes:
•Aug. 3-5: Milling off the southbound lanes from Vale to Dorothy.
•Aug. 6: Starting about 4 a.m., crews plan to begin milling the intersection of County Line and Dorothy. After the pavement is milled off, crews will pave that intersection with the goal of having the work done by 1 p.m.
•Week of Aug. 8: Pave County Line from Vale to Dorothy and place the permanent striping and utility adjustments.
“This is a proposed plan, but weather and other circumstances may cause the dates and process to change,” according to the city.
Beavercreek and Kettering are each paying 20% of the local share to expand that section. Federal funds are covering the remaining widening costs, officials have said.
The work, which started in June 2021, has reduced traffic to one lane in each direction, with officials suggesting alternative routes.
But both cities say the expansion will help bring jobs to the 1,250-acre research park, which straddles both jurisdictions.
Those businesses include technology-based companies and military contractors with near Wright-Patterson Air Force Base, officials have said.
