As a local public works agency headquartered in Columbus, Ohio, the Franklin County Engineer's Office is responsible for the maintenance and construction of 271 miles of county roadway and 351 county bridges, as well as upkeep of all county ditches, drains, retention basins, and other storm water facilities within the right-of-way of county roads in unincorporated areas. To meet the continuing development and infrastructure needs of Franklin County, the Engineer's Office utilizes the latest technologies for determining and maintaining roadway centerlines and boundaries; retracing and setting new monuments for original public land surveys; preparing geographic information system mapping for real estate tax assessments; and establishing precise countywide horizontal and vertical control to maintain uniformity in construction, surveying, and mapping.

Lane Avenue Bridge

The Lane Avenue Bridge, spanning the Olentangy River on The Ohio State University Campus, was opened on November 14, 2003.

The cable-stayed structure, built by the C.J. Mahan Construction Company, is 370-feet long and 112-feet wide. The pier towers stand 145-feet above the river and hold ten multi-strand cables on each side of the bridge to support the deck. More than 36 miles of post-tensioned cable strands are embedded within the concrete to strengthen the deck and edge girders.

Jones-Stuckey Ltd, Inc. prepared the construction plans.

On May 21-22, 2003, a 550-ton capacity crane was used to install a 52-ton (104,000 pound) cable anchorage assembly atop each of the concrete pier towers. The Engineer News Record cited the anchorage assemblies as the heaviest single pieces of steel ever to be galvanized, and lifting them into place at such a height and angle was a major hurdle in building the bridge.
