Replacing an Aging Structure

For the replacement of a two-span concrete encased, multi-stringer bridge, we provided preliminary and final design, traffic studies, environmental, and construction support services. The new bridge consists of a single-span, adjacent box beam structure located on the existing alignment. Our design included 150 linear feet of natural stream channel and riparian buffer construction enhancement, as well as approach roadway and guiderail updates.

Our environmental services included stream reviews, fluvial geomorphologic assessment, and hydrography and hydraulic analysis for the J-vane design at the bridge. We also performed construction review for the select quarry rock material and oversight during rock J-vane placement. This instream rock vane is located immediately downstream of the City of Lebanon and subject to high-flow discharges resulting from an urban/impervious watershed. We worked with the contractor to direct and support the rock vane construction and in-channel scour hole placement.
