Structures Field Review Site 02 2014	Iredell,	Bridge on Hillside Ln over Fourth Creek
Issues: Long two-span curved girder bridge with top flange lateral bracing in exterior girder bays along entire length of bridge Action Item: Reevaluate guidance on top flange lateral bracing; may only be required in parts of the span (such as near the interior bent for multiple span bridges), depending on the assumed girder erection/construction sequence Issues: At another bridge site on this project where MSE walls were used, the piles were driven before backfilling; when backfill was applied, the piles moved; temporary bracing was required to stabilize Action Items: · Provide a note on plans to require temporary bracing of piles when pile driving precedes backfilling · Collaborate with Geotech to determine the height of an MSE wall that would require pile bracing
