The Havre de Grace Main Street program is one of a network of statewide, citywide, and countywide Main Street programs, with more than 2,100 active Main Street programs nationally.
 
All have been chartered by the National Trust for Historic Preservation over the past several years to revitalize their downtown business districts and preserve their historic character.
 
Main Street is a national movement that has spanned three decades and taken root in more than 2,000 communities - a movement that has spurred $49 billion in reinvestment in traditional commercial districts, galvanized thousands of volunteers, and changed the way governments, planners, and developers view preservation.

Over the past 30 years, the National Trust Main Street Center has overseen the development of a national network of coordinating programs that today includes 37 statewide programs, seven citywide programs, and two regional programs. These coordinating programs help cities, towns, and villages revitalize their downtown and neighborhood business districts. Coordinating program staff help build the capacity of local Main Street programs, expand the network of Main Street communities, provide resources and technical assistance, and work with the National Trust Main Street Center to explore new solutions to revitalization challenges and respond to emerging trends throughout the nation.
