Peger Road Bridge
Fairbanks, AK
In 1991, the Peger Road Bridge over the Chena River was widened. Construction included the extension of two interior bridge piers on new piles in the river. Following reports of deficient concrete in the pier extensions, the Alaska DOT closed the affected lanes of the bridge, notified the contractor of the problem, and requested a plan for corrective action. They retained SGH to determine the extent, significance, and cause of reported deficient concrete in the pier extensions and monitor the repairs designed and undertaken by the subcontractor who constructed the widened piers. SGH, in consultation with the inspection divers, used an underwater survey with hydro-demolition equipment to determine the scope of deficient concrete. Underwater repairs were completed in one month, before winter arrived.
