DESCRIPTION: WHKS completed a major bearing replacement project on the historic Centennial Bridge, ensuring the continued safe operation of this important community link. Constructed in the 1940s, the Centennial Bridge serves as a vital crossing over the Mississippi River between Illinois and Iowa. However, age and wear had compromised the expansion bearings of the bridge’s tied arch spans, affecting the structure’s ability to expand and contract with temperature changes.
