During the Rock n Roll Marathon event held in the Nation's Capitol every year there will be several road closures as well as street detours being conducted in Downtown Washington D.C. Unfortunately the Company has no control over these road closures and we will be doing our best to ensure that you still have an opportunity to explore the city of Washington DC.We hope that these road closures do not inconvenience you too much and you can still enjoy your experience with Open Top Sightseeing.
