OC Loop Segment D Marks a Major Milestone for Orange County Connectivity

November 11, 2026

Mark Thomas helped bring OC Loop Segment D to life, closing a key gap in Orange County’s planned 66-mile bikeway and creating a safer, more accessible connection for cyclists and pedestrians.

Mark Thomas joined Orange County Public Works (OCPW) to celebrate the ribbon-cutting for OC Loop Segment D, an important connection in Orange County’s vision for a continuous 66-mile bikeway.

Our team provided final design and PS&E services for Segment D, helping transform a key gap in the network into a safer, more accessible multimodal connection. The project connects the La Floresta Development trail at Imperial Highway with the El Cajon Trail at Bastanchury Road, and incorporates a 12- to 15-foot-wide bikeway, a 133-foot-long precast box culvert undercrossing, over 2,500 lineal feet of permanent rustic steel sheet pile walls, lighting, ADA access, bicycle and pedestrian signals, landscaping, drainage, and other enhancements.

OC Loop Segment D represents an important step toward a safer, more connected Orange County. By creating more opportunities to bike, walk, commute, and enjoy the outdoors, the project will improve access to communities and destinations throughout the county for years to come. Congratulations to OC Public Works and all of the project partners on reaching this exciting milestone.
