Stewart Parkway Road Realignment; Roseburg, OR

Stewart Parkway is an arterial that reduced from five lanes to two lanes with a very sharp S-curve, limiting site distance. It was a major safety concern for the City of Roesburg. Century West provided engineering and full construction management services for roadway, stormwater quality and stormwater quantity facility improvements. Portions of the 3,500 feet of improvements were highly floodprone, which the project addressed through the construction of large multi-acre detention ponds in existing City-owned riparian land.

The $4.87M project was recently constructed to provide four travel lanes south through a realigned S-curve, along with new sidewalk and bike lanes throughout the project limits. The road was closed for 3 months which was instrumental in keeping the project under budget and ahead of schedule. This complex project involved multiple street sections, widening of a bridge over Newton Creek, retaining walls, new stormwater conveyance system, water quality facilities, reconstruction of signalized intersections, ROW acquisition, and wetland mitigation. Adding to the complexity of this project, two large regional detention facilities were constructed to reduce downstream flooding along Newton Creek. Flows from the creek were diverted to these facilities by two large diameter pipes and a diversion structure adjacent to the new bridge abutment.
