Maryland Route 99 Investigation


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, and the results will help guide future county and state actions.

Howard County and consultant personnel have performed field observations – both in person and using aerial drones – to assess current conditions along Maryland 99, and have begun to analyze and model current traffic levels in the corridor, as well as identify was to improve pedestrian and bicycle access in the area. Additional field observations will take place after the school year begins, and the project team will then develop recommendations to present later in the fall.
