The bridge carrying County Road 20 over Tannery Creek was comprised of two (2) 10-ft diameter corrugated metal pipes with 4ft of embankment between them. The total length of the pipes was 142 ft and were covered with over 12 ft of highway embankment. The new structure is a 28-ft span precast concrete three-sided structure founded on piles. The clear span structure was selected to meet current hydraulic and regulatory standards, and to reduce the likelihood of future debris snagging at the structure. A natural stream bottom was provided to support the growth of aquatic life along the watershed. Highway work was limited to tying into the existing roadway profile and horizontal section.
