SR 810/Hillsboro Boulevard Resurfacing

Erdman Anthony provided engineering design and post-design services for the resurfacing, restoration, and rehabilitation of SR 810/Hillsboro Boulevard, from SR 7/US 441 to SR 845/Powerline Road. The six-lane divided urban principal arterial has suburban commercial and suburban residential context classifications.

The project entailed carving out 7-foot-wide buffered bike lanes in both directions by reducing the travel lane widths from 12 feet to 11. Other improvements included:

• Milling and resurfacing the existing asphalt pavement
• Reconstructing noncompliant curb ramps
• Upgrading existing pedestrian curb ramps and installing detectable warning surfaces
• Repairing sidewalks
• Resetting guardrails that did not meet current standards
• Retrofitting lighting at signalized intersections
• Upgrading pedestrian signalization and push buttons at signalized intersections
• Making minor drainage modifications resulting from upgraded pedestrian ramps
• Upgrading existing strain pole signals on Lyons Road with mast arms

The wider buffered bike lanes and restored roadway have boosted the corridor’s multimodal mobility. The roadway pavement’s design life has been extended by 20 years, and the mast-arm upgrades are poised to improve safety and traffic flow at the Lyons Road intersection. The lighting retrofits at the signalized intersections are also slated to improve safety.
