St. Mary's County Department of Public Works & Transportation
Service Area Map
An interactive Service Area Map has been provided to geographically show the progress crews are making
on county maintained roadways. The program allows citizens to zoom in and / or out as well as search for a specific road name. As roadways are
initially treated / plowed, the roadway(s) will be shaded purple.
This map is updated every fifteen minutes.
The DPW& T is responsible for snow removal and ice control on over 1,500 County-maintained roadways encompassing more than 1,400 lane miles within four Service Areas (North, Central, West & South as shown below). Snow removal is considered a Top Priority of the Department.
When severe weather
occurs in St. Mary's County, DPW&T's computerized system tracks the
progress of snow removal operations (providing the data for the automated
map you see here), as service crews are dispatched and completed work
in their respective Service Areas. While speed and efficiency are important,
DPW&T employees are instructed to maintain safety standards as they
work to maintain safe roads for citizens and visitors.
This map is for informational purposes only and the numbers reflected are estimates of County-maintained roadways that are being treated, plowed and/or have been visually inspected. As a part of our Snow Spotters
Program, the DPW&T relies on you to call and report changing roadway
conditions; your call helps us ensure that areas are not unintentionally
Roads: Residents are advised
that although residential subdivision streets are
plowed and salted, they could remain in a snow
packed condition. Snow packed means that the snow
has been compacted to the road’s surface by
vehicular traffic. In low temperatures, especially
below 15-20 degrees, salt is not very effective.
With or without salt, these roads sometimes do not
get down to bare pavement until the snow melts. As
the snow melts, the snow surface usually begins to
break apart into smaller sections. At that time, the
roads may either be re-plowed or left to naturally

Arterial streets, major collector and urban commercial
roadways are our
first priority; followed by secondary
residential streets and minor collector roads; local
roads in subdivisions such as courts and dead end streets
are addressed once the first two priorities have been
satisfactorily completed as they are the least traveled.
