Late summer or early fall is expected to see completion of the central tower of the Dublin pedestrian bridge that will span the Scioto River.

Construction began early last year on the bridge, which will provide a connection on both sides of the river to the planned Dublin Riverside Park, said Megan O'Callaghan.

Dublin has a construction contract for $22.6 million with Kokosing for the bridge project, she said.

When complete, the s-curve suspension bridge will be 760 feet long. Of that length, the suspended portion of the bridge will measure 500 feet long.

Evidence of the bridge's progress already can be seen.

Kokosing has constructed a stone causeway from the river bank into the water, O'Callaghan said. Crews will work from the causeway as construction progresses. It will be removed when the project is complete.

Concrete piers have been built on the west side of the river, and that work is nearly complete, O'Callaghan said.

The central tower, or pylon, will be the bridge's focal point at 169 feet high, she said. That tower is halfway complete.

"There's a lot of work going on onsite, but there's also work proceeding in other states and in other parts of the world," O'Callaghan said.

Bridge beams are being fabricated in Tampa, Florida, O'Callaghan said, while suspension cables are being fabricated in Italy.

Between summer and early fall, the steel will be delivered from Tampa, she said. The suspension cable meanwhile, will begin being installed over the winter.

Next spring, work will include pouring concrete, painting steel and installation of lighting fixtures and handrails, O'Callaghan said.

The city expects the bridge to be complete by summer 2019, she said.

The bridge's purpose, O'Callaghan said, is to provide connectivity and mobility by connecting the development on both sides of the river as well as a better connection to the historic district.

"This bridge will serve as a landmark for the city," she said.

Scott Dring, executive director for the Dublin Convention & Visitors Bureau, said his organization has been promoting and marketing the new downtown Dublin for several years. Walkability of this area, he said, is going to be enhanced with the completion of the bridge.

"It is just going to make it such a unique destination here in the midwest," Dring said, for not only in-state visitors, but also those nationwide.

"To me, the bridge not only serves as an icon, but it's also going to help generate tremendous revenue and jobs for the city," Dring said.
