Waco Suspension Bridge Cable Replacement

Promo Icon 2 Updated

The existing Waco Suspension Bridge was built in 1914, with the towers dating back to the original structure from 1859. The bridge is an ASCE Civil Engineering Landmark and Recorded Texas Historic Landmark.

In need of repair, the bridge will undergo a deck replacement, as well as the replacement of the entire cable and hanger system, while retaining the existing stiffening truss.

As specialty engineer on the project, Modjeski and Masters will provide final design for the cable and hanger system, as well as the associated erection engineering. The team is working with the specialty contractor and their selected fabricator to develop the safest and most cost-effective details—including the methods for removal of existing cable and hangers and the installation and tensioning of the new cables and hangers.

The Modjeski team began design work on the project in January 2020, with the removal of the existing elements slated to begin in late 2020. The new material will be fabricated in early 2021, and the installation of the new cable and hangers is slated to begin around September 2021. The project in its entirety has an estimated value of $12.4 million.
