About this file
This bridge inspection report documents the results of a routine inspection of the Teklanika River Bridge carried out on June 21, 2021. The six-span steel stringer bridge was built in 1955 and reconstructed in 1998. It carries the Denali Park Road over the Teklanika River and has a structure length of 334 feet. The inspection found paint peeling and rust on exposed steel, deterioration of expansion joint filler, and cracking and spalling in the concrete substructure. The inventory and operating ratings were determined to be 30 and 50 tons respectively. Routine biannual inspections are scheduled.
The related federal contract opportunity is a solicitation released by the Department of Transportation Federal Highway Administration seeking proposals for improvements to the Polychrome Area in Denali National Park. Responses are due by the specified date. The solicitation and attached documents provide details on the required construction services and materials. Compliance with typical terms and conditions for federal procurement is addressed.
