We designed the reconstruction of Hillcrest Drive in Bartlesville, Oklahoma. Our work stretched from East 18th Street and the Caney River and included repurposing a portion of the existing roadway as an extension of the Pathfinder Parkway pedestrian trail system.

This connected the new trail to the existing trailhead north of Hillcrest Drive along Shawnee Avenue. A major component of the project was the hydraulic modeling to avoid inundation of the new roadway by nuisance floods and determining the hydraulic impacts of the proposed improvements to the floodway and floodplain of Caney River and Sand Creek.

A major component of the project was the hydraulic modeling to avoid inundation of the new roadway by nuisance floods.

The initial Hillcrest Drive corridor between East 18th Street and the Caney River is classified as a major arterial street and carries up to 8,300 vehicles per day on a narrow two-lane open-section roadway without shoulders. Steep roadside ditches contributed to degradation of existing roadway base materials along both sides of the corridor requiring regular patching to maintain a safe route.

Reconstruction and realignment of this corridor improved traffic safety and operations by providing wider travel lanes, and shoulders along both sides of the corridor, and improve roadside safety by providing safe drainage side slopes consistent with the AASHTO Roadside Design Guide and the ODOT Roadway Design Manual.

The improvements to Hillcrest Drive consisted of widening the existing narrow roadway section to two 12-foot-wide drive lanes with 6-foot-wide paved shoulders along both sides of the corridor. This transitions from an open-section roadway to a closed-section street with concrete curb and gutter to match existing section at the Caney River bridge approach. It was pertinent to extend existing drainage structures as needed to accommodate the wider pavement and roadside safety slopes.

Portions of existing Hillcrest Drive between the horizontal curve near the East 20th Street intersection and the Caney River bridge approach slab were rehabilitated in place to serve as a pedestrian trail that is now part of the City’s Pathfinder Parkway Trail.

Other services included in this project included survey, geotechnical, and floodplain modeling.
