I-77 Cleveland Innerbelt CCG6B

Largest girders set by Kokosing


The project consisted of replacing the Broadway Avenue (SR-14) structure over IR-77 as well as reconfiguring the ramps from IR-490 EB/WB to IR-77 SB to provide standard lane width and merge distances. The existing ramp from Broadway Avenue to IR-77 SB was reconstructed as a Frontage Road to Pershing Avenue. The mainline lanes of IR-77 SB, adjacent to the ramp work, were resurfaced as part of this project and a multi-use path constructed along the Frontage Road.

To accommodate grade changes and significant existing and proposed utilities, four different wall types were designed, including a jet grouted wall and a soldier pile wall to span an AT&T duct bank.

The project scope included many key milestone dates, utility conflicts, and the design of a highly skewed, 400-foot two-span bridge. The milestones were met by delivering the project design plans in multiple buildable units, allowing portions of the project to be constructed in advance.

This project was the recipient of:

  • Northeast Ohio Association for Bridge Construction & Design (ABCD), Outstanding Bridge Award, 2019
  • Don Conaway Partnering Award, Honorable Mention, 2020
