Ironton Russell Bridge (Oakley C. Collins Memorial Bridge)
Ironton, Ohio - Russell, Kentucky
Project Description
The Ironton Russell Bridge is a cast-in-place concrete cable stayed bridge over the Ohio River with structural steel approaches connecting the towns of Ironton, Ohio and Russell, Kentucky.
The bridge provides two 12-ft driving lanes and two 4-ft shoulders; a driving lane and shoulder in each direction. Span lengths for the approaches vary widely as they cross numerous (6) rail lines, the Ohio River levee and city streets. On the Kentucky side the spans are 140-ft and 235-ft; in Ohio the spans are 110-ft, 144-ft, 186-ft and 144-ft.
The approach bridges are founded on small diameter drilled shafts (Kentucky) or steel pile (Ohio). The main span unit consists of three spans; two flanking spans at 370-ft and the center span of 900-ft. The main span unit is supported by two cast-in-place, 316-ft tall, diamond shaped towers, founded on large diameter drilled shafts with rock sockets. The 900-ft main span is the longest span the Ohio DOT has built.
The original contract value for construction of the new structure and removal of the existing was $81,266,742.05, with Brayman Construction Corporation the low bidder.

Our Role
Jason Hatcher worked with construction engineer Finley Engineering Group, performing a constructability review of the bridge towers, and the precast concrete cable stay blocks. Jason then oversaw development of revised construction shop drawings of these areas. Jason also visited the precast yard in Pennsylvania to inspect and resolve constructability challenges related to the innovative precast cable stay blocks designed by Finley.
