2LMN worked as a subconsultant to EMH&T  for the replacement and modernization of traffic signals along Hilliard-Rome Road and Roberts Road. Improvements include upgrading signal infrastructure and implementing flashing yellow arrow signal heads to improve intersection operations and safety. The project is located along the City of Columbus Vision Zero High Injury Network, where improvements are intended to reduce serious crashes and enhance safety for motorists, pedestrians, and bicyclists.
