Overview
The Howard County Department of Public Works Traffic Engineering is proposing intersection improvements at the Guilford Road and Old Columbia Road intersection through the implementation of a mini-roundabout design to enhance intersection safety, improve traffic operations, and provide better multimodal connectivity. The project is intended to address existing operational and safety concerns associated with the current intersection configuration while maintaining efficient traffic flow through the area.
Project Purpose
The existing intersection experiences challenges related to vehicle turning movements, intersection visibility, and driver yielding behavior. The proposed mini-roundabout will modify the existing intersection geometry by introducing a circular roadway configuration that requires vehicles to travel at reduced speeds and navigate the intersection through a controlled yield operation. This design is expected to reduce conflict points, minimize the potential for severe angle crashes, and improve overall intersection safety for all roadway users.
The project also supports Howard County’s commitment of implementing Complete Streets Design by considering the needs of pedestrians, bicyclists, and motorists through improved intersection accessibility and safer roadway operations. Related transportation improvements in the Old Columbia Road corridor have included efforts to enhance roadway capacity, pedestrian connectivity, and multimodal access.
Design and Public Comments
The concept design for the mini-roundabout project and comment sheet are available here:
Community Meetings
June 17, 2026. The DPW Traffic Engineering held a Public Open House community meeting at Kings Contrivance Community Association Amherst House to present mini-roundabout concept design.
Next Step
The project is currently funded and moving forward into the design phase. The current plans represent approximately 30% design completion, which reflects the preliminary engineering stage of the project. During the next phases, the design team will continue to evaluate and refine the roadway geometry, drainage, pedestrian and biker accommodations, signing and pavement markings, and other associated improvements based on engineering review and stakeholder coordination.

Resident concerns related to excessive vehicular speeds continue to be a major issue along Howard County’s residential roadways. In an effort to address these concerns and support Howard County’s Strategic Road Safety Plan, Department of Public Works (DPW), in cooperation with the Howard County Police Department, Department of Fire and Rescue Services, Office of Transportation, and the Howard County Public School System, has updated their Traffic Calming Policy to combat excessive vehicular speeds.
The Howard County Department of Police recognizes that excessive speed and other traffic violations in residential areas are a source of concern to the community. The Department will take an active role in enforcing applicable laws, educating the public and making suggestions for road engineering improvements. Law is the principal means of speed control.
- It is the responsibility of each patrol officer to enforce motor vehicle laws, particularly those involving excessive speed. Radar training and equipment will be provided to as many Patrol Division officers as possible to assist them in this effort during the normal course of their patrols. Supervisors who become aware of speed problems in specific communities will direct their officers to conduct speed enforcement in those areas.
- Specific speeding complaints in residential areas will be directed to the Traffic Enforcement Section, which will keep a file of all such complaints.
- A Radar Road List will be published each month to direct the enforcement efforts of patrol officers assigned radar or other speed measuring devices. Each road will require a minimum amount of enforcement time. The Supervisor of the Traffic Enforcement Section will approve roads for inclusion on the list based on the number of complaints received, past enforcement history on the road, and analysis of any speed surveys conducted by the Department of Police or Traffic Engineering.
- In addition to the monthly Radar Road List, the Traffic Enforcement Section will identify roadways for officer enforcement, including roads on which speeding persists or is of such a nature that it requires immediate and sustained enforcement. These may also include roads in which the use of unmarked vehicles or special equipment is necessary.
- At the beginning of each school year, the Department of Police will institute a special speed enforcement program on the roadways surrounding the County’s schools. This presence will serve to cite violators and to remind drivers that school is back in session and conformance to the speed limits is critical for student safety. This program will be accompanied by news releases.
- Revised: 10/31/2013
Traffic Reporting
HCPD now offers residents the opportunity to report concerning traffic situations throughout the county. Each report will be reviewed by a Traffic Enforcement Section officer to determine next steps. Reports can be filed using the link below.
FAQs - Traffic Calming
The Institute of Transportation Engineers- Traffic Engineering Council presents tips on stop signs. Contact the Bureau of Highways- Traffic Engineering Division for more information at 410-313-2430. The Traffic Division can assess the need for traffic calming and determine how stop signs will affect the flow of traffic.
The Traffic Engineering Division can conduct a study and determine the most efficient stopping mechanism at a particular intersection, to see if a four-way stop would be the best fit. Contact the Traffic Engineering Division for more information at 410-313-2430.
The Traffic Signal Warrants list summarizes the basis for new signal installation. Please contact the Traffic Division at 410-313-2430 if you believe an intersection would be eligible for signal installation. The Traffic Division will want to determine the most efficient and safe way to keep the driving public moving.
Speed limits are carefully studied for safety, and are set as they are for a reason. However, in the event that an area needs to be reassessed, the Bureau of Highways can help. The Traffic Division can analyze a neighborhood for safe speeds, depending on a variety of factors including traffic volume, road designation (Arterial Roads vs Major Collector Roads), prevailing speed (85th percentile), and proximity to schools. If you would like your neighborhood assessed for traffic calming/speed reduction, please contact the Traffic Division at 410-313-2430.
School Zones
Maryland law defines a school zone as a roadway within a half-mile radius of a school where State Highway Administration or the local authority may set maximum speed limits. Established school zones are marked with street signs indicating the zone boundaries and applicable speed limits. Howard County's automated speed enforcement positions "speed cameras" on roadways that either front schools or border school properties or roadways along student walking routes that are designated school zones. Each school zone is clearly marked as a school zone and as an automated speed enforcement (ASE) location. Links to school zone maps are provided below.
