Injecting epoxy into concrete cracks under Burnside Bridge.
Hamilton Construction's team completed repairs to concrete cracks under the Burnside Bridge over closed lanes of I-5 south over the April 14-17 weekend.  Epoxy was injected into many cracks to keep out water that can rust steel rebar inside the concrete.  Decades of dirt and exhaust were cleaned from the concrete before the epoxy was injected into ports positioned along the cracks.

During the second and final weekend closure of I-5 south April 21-24, the contractor will mount strips of carbon fiber reinforced polymer over the areas of damaged concrete to prevent chunks of concrete from falling onto the freeway in the future.
