LEONARDTOWN, MD – The Department of Public Works and Transportation has announced plans to construct a roundabout at Mount Wolf Road and Triangle Drive intersection starting Wednesday, July 5, 2023. Anticipated to last approximately 60 days, the project aims to enhance traffic flow and safety in the area. While the roadways will remain accessible during construction, commuters should anticipate changes in traffic patterns and potential delays. The department will also deploy Variable Message Boards to serve as a visual reminder to motorists.
The roundabout installation initiative is part of the ongoing efforts by the St. Mary’s County Department of Public Works & Transportation to improve road infrastructure and address traffic congestion issues. By implementing a roundabout at the busy junction, authorities hope to facilitate smoother traffic movement and reduce the likelihood of accidents.
During the 60-day construction period, the roadways will remain open to traffic, but motorists are advised to exercise caution and prepare for potential disruptions. Temporary traffic diversions and alternate routes may be implemented to accommodate the construction activities. The Department of Public Works and Transportation urges drivers to stay informed about the changing traffic patterns and plan their journeys accordingly.
The deployment of Variable Message Boards near the project site aims to provide timely notifications and reminders to motorists. These electronic signs will convey essential information about the ongoing construction and guide drivers through altered traffic routes. Commuters are encouraged to pay attention to these message boards and follow the indicated instructions to ensure a smooth and safe travel experience.

The department’s representatives will be available to provide project updates, address concerns, and assist residents and stakeholders throughout the construction.
