Project Summary
The Route AC project will provide improvements along the corridor between Route 67 (Lindbergh) and I-270 to address rising crash patterns and improve safety for motorists and pedestrians.
A Road Safety Audit (RSA) is being conducted to evaluate improvements, which may include resurfacing, along with sidewalk, signal and other safety upgrades.
