Together, we are making life better for all of Dorchester County.
The Dorchester County Transportation Sales Tax Program is our path to progress for a thriving and mobile Dorchester County that connects our community.
The 2022 Dorchester County Transportation Sales Tax allows the County to make significant strides in addressing current and future transportation needs in Dorchester County.
Dorchester County’s Transportation Sales Tax Program will fund road improvement projects of local and regional significance, dirt road paving projects, pavement preservation, and intersection and safety improvement projects. We are committed to paving the way toward progress and providing better transportation solutions for the community.
