Study to Examine Road Widening, Signal Needs in Lewis Center

Share Article

Delaware County hires Woolpert to gather and analyze data, and develop feasible roadway alternatives for South Old State Road.

This LiDAR-generated, gridded-surface image shows South Old State Road at Orange Road. The color variation is based on elevation: red is high elevation, while yellowish-green is low elevation.

LiDAR produces better and tighter data, with more than three collection datapoints per meter, This will give us more detail regarding drainage and runoff, and more information on roadway issues.

Delaware County has contracted with Woolpert for road improvement studies on a mile-and-a-half stretch of South Old State Road from Orange Road north to Lewis Center Road in Lewis Center.

Woolpert will collect and analyze data to determine whether the two-lane road should be widened, up to five lanes at select areas, and if intersections require signals, roundabouts or turn lanes.

“Our role is to look at traffic, accidents, delays, environmental issues, concerns for right-of-way, overall project cost, (etc.),” said Ron Mattox, Woolpert project director. “Then we can develop feasible roadway alternatives for two lanes or three lanes or five lanes to alleviate existing traffic and safety issues.”

U.S. Census data shows that Delaware has been among the fastest growing counties in Ohio for years, and multiple subdivisions have been built along South Old State Road.

“We’ll be looking at five major intersections to determine if a signal is warranted or a roundabout would provide the necessary capacity and safety,” Mattox said. “Plans also call for a 10-foot-wide multiuse path, with a sidewalk on the opposite side.”

Woolpert—a national architecture, engineering and geospatial firm headquartered in Dayton—has worked with Delaware County in the past. The firm provided aerial imagery and mapped this stretch of road three years ago as part of a countywide project using light detection and ranging (LiDAR).

Earlier this year, the South Old State Road corridor was reflown to get higher resolution imagery and more precise mapping.

“LiDAR produces better and tighter data, with more than three collection datapoints per meter,” Mattox said. “This will give us more detail regarding drainage and runoff, and more information on roadway issues like sight distance—whether drivers can see over an upcoming hill, if there are trees or a building blocking a turn, etc.”

Woolpert will use the LiDAR mapping to develop alternatives for South Old State Road improvements and create documentation for the county. The county will share its findings with the public once the study has been completed.

The study should take about eight months. Roadwork is expected to take place in 2019 and is dependent on funding.
