Graff Bridge Preservation Project- Coming Soon!

Armstrong County, Pennsylvania, USA
MCS

Modified Concrete Suppliers is proud to be part of the upcoming preservation of the historic Graff Bridge on Route 422 over the Allegheny River in Kittanning, PA.

This bridge last received a Latex Modified Concrete (LMC) overlay in 1975—proving the remarkable durability of LMC with nearly 50 years of performance.

In fall 2025 and spring 2026, MCS will once again supply and place a new LMC overlay to ensure this vital structure continues serving the community for decades to come. Stay tuned for a full project update!
