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.

The Howard County Office of Transportation is leading the investigation in coordination with the Maryland Department of Transportation and the Howard County Departments of Public Works and Planning and Zoning. Howard County plans to complete the investigation in the fall of 2018.

Open House Materials:

On Tuesday, February 6, 2018, the Office of Transportation hosted an open house from 5 PM to 8 PM at the at the George Howard Building (3430 Court House Drive, Ellicott City). The Open House provided a venue for community members to talk to staff and for staff to learn as much as possible from area residents to ensure the project team is are aware of the issues experienced by the people who live in the area and know it best. At the open house the Office of Transportation and MDOT-SHA had tables and boards with information we have gathered such as traffic volumes and crash data. Attendees had the opportunity to review the information, and to discuss issues and concerns one on one with county and state staff.
