Boones Ferry Corridor Bike Lane and Sidewalk Improvements Tualatin, Oregon

With the primary focus of enhancing the roadway while making it more pedestrian and bicycle friendly, improvements along Boones Ferry Corridor were also designed to account for identified ADA deficiencies. As part of the Tualatin Moving Forward bond program, Otak served as the lead design engineer for improvements to this 2-mile corridor in Western Oregon.

A Practical ADA-Focused Design for Pedestrian and Bicycle-Friendly Corridor Improvements

While avoiding a full construction of Boones Ferry Road, the project provides practical, cost effective solutions to address bike and pedestrian deficiencies found scattered throughout the corridor. Initial analysis found gaps in bike lanes, deteriorated asphalt paths, and non-compliant curb ramps along the corridor that stretches south from Tualatin Sherwood Road to Norwood Road. Along with road widening to provide continuous bike lanes and sidewalk improvements, the multi-phase project also makes improvements to greenway paths, pavement, stormwater conveyance, traffic signals, signing, striping, and landscape. The final design of the project also retrofits curb ramp to bring existing facilities up to current ADA standards. In total, ramps are replaced at 33 corners, including four signalized intersections with pedestrian push button improvements. To further enhance pedestrian safety, the design adds two pedestrian activated rectangular rapid-flashing beacons (RRFBs) as well as pedestrian lighting along a greenway path adjacent to Boones Ferry Road. The design of the project overcame challenges including steep slopes for ramps, right-of-way constraints, and numerous utility conflicts.
