Administration appreciates customers’ patience during construction as we work to improve Maryland’s transportation system. Drivers are asked to stay alert, stay focused and be aware of reduced speed limits and changing driving patterns in work zones. Slow down or move over for emergency vehicles and other vehicles displaying warning lights. It’s the law.
Motorists in need may dial #77 on their mobile devices for roadside assistance.
