Title

Jordan Road at Little Creek Bridge & East Fork Road at N Fk of E Fk Hayfork Creek Brigde Replacements

Description

Trinity County, in Cooperation with the Federal Highway Administration (FHWA) Central Federal Lands Highway Division (CFLHD), is proposing to replace two bridges: the existing Bridge 5C-187 on Jordan Rd over Little Creek and Bridge 5C-157 on East Fork Rd over the North Fork of East Fork Hayfork Creek. New bridges would improve public safety for traffic crossing Little Creek and North Fork of East Fork Hayfork Creek by replacing functionally obsolete and/or structurally deficient bridges with new structures that meet current design standards. To meet design standards, the East Fork Road proposed bridge structure would be 20 ft wide, consisting of one 16-ft travel lane and two 2-ft railings. To meet design standards on the Jordan Rd Bridge over Little Creek, a 28-ft wide two lane structure with two 11-ft travel lanes, two 1-ft shoulders, and two 2-ft railings is proposed. The structure design for each bridge would accommodate a 50-yr flood event with 2 ft of freeboard; i.e., the low-beam elevation for the new structure would be at least 2 ft higher than the 50-yr flood elevation. Minor approach work totaling no more than 350 ft from each end of the bridge abutments for the East Fork Road Bridge is anticipated, with the potential for improvements to enhance curvature and sight distance. Aggregate would be placed on the roadway. On Jordan Road, minor approach work totaling no more than 600 ft (approximately 200 ft on the south side of the Little Creek Bridge and 400 ft on the north) would be completed and the existing pavement along Jordan Rd would be replaced.
