Howard County is undertaking an investigation into the transportation challenges facing residents in the MD 99 corridor. In 2017, during public meetings on the County’s 2018 Priority Letter, many residents shared their concerns about the safety and congestion challenges on MD 99, especially in the section between Marriottsville Road and the US 29/MD 99 intersection. Recognizing these challenges, the County initiated an investigation into the traffic, safety, and congestion challenges on the MD 99 corridor. The investigation is focused on gathering data and information and the impacts on residents. The results will help guide future county and state actions.
The MD 99 Corridor Investigation originated in response to long-standing concerns by residents in neighborhoods bordering the corridor, as well as broader public concerns regarding safety and traffic in the corridor.
