About this file
This is a Road Bridge Inspection Report for the East Fork Dry Run Bridge located in Wythe County, Virginia, on Route 14 at milepost 0.1600, conducted by the USDA Forest Service, Region 8 (George Washington & Jefferson National Forests) on September 17, 2024. The structure (ID: 080814000003216) is a single-span, reinforced concrete slab bridge built in 1935 and reconstructed in 1987, measuring 25 feet in overall length with a 23-foot maximum span and 16-foot deck width. The bridge carries one lane of two-way traffic with a design load of HS20-44 and an average daily traffic count of 10 vehicles.
The inspection identified several maintenance and safety concerns requiring recommended work items: routine bridge inspection every 24 months, repair of approach settlement (A1), placement of aggregate surfacing, and upgrade of bridge railing (150 linear feet). Condition ratings indicate the deck is rated 7 (good), superstructure 7 (good), and substructure 6 (fair to good), with specific defects including hairline cracking on the deck underside, chemical scaling on footings, abutment erosion with flow attacking A1, bank erosion on both sides of the stream, impact damage to the upstream bridge rail, missing spacer blocks, and a concrete spall near the downstream abutment bearing. The scour critical bridge code is 4, with footing undermined conditions noted and riprap protection placed since the last inspection in 2015. Load ratings show the bridge can safely accommodate standard truck types (Type 3 at 27 tons, Type 3S2 at 41 tons, and Type 3-3 at 53 tons). The structure remains open with no restrictions, and the next routine inspection is recommended within 24 months.
