TYLin provided engineering and permitting assistance for a Class I bike path that closes the gap in the 3-mile, multi-use Sweetwater Bikeway in San Diego, California.
On behalf of the San Bernardino County Transportation Authority (SBCTA), as part of the Regional Bike Plan Early Action Program, TYLin designed the bike path to include two 4-foot asphalt concrete lanes, two 2-foot concrete shoulders, and a 5-foot buffer separating the bike path from vehicular traffic.
Design elements included road widening and transitioning from the on-street bike lane to the bike path, new on-street parking, retaining walls, traffic signal modifications, striping, wayfinding signage, curb ramps, sidewalks, and drainage improvements.
- TYLin assisted with stakeholder outreach and federal funding application and approvals.
- Ongoing communication with utilities avoided impacts on other utility work within project limits.
- Close coordination was required with SBCTA, the city, and a local shopping mall owner.
- TYLin managed the landscape architect that designed new irrigation and landscaping.
