Contech worked with the Alaska DOT to extend an existing structure supplied by Contech in 1976. The project aimed to realign the road for improved safety and visibility. A value-engineered proposal was presented to the State by the contractor and Contech to eliminate elbows in the new structure in order to accommodate a curved track.

The proposal included skew cutting the end of the new structure to be attached to the existing structure headwall, with the connection being made with a reinforced concrete collar. End treatment of the new end consisted of a Metric Sheeting headwall and Bin-Wall™ Type 1 wingwalls. Peninsula Construction, of Kenai, Alaska, provided the assembly and backfill for Herndon and Thompson on this live track.
