MarylandâÂÂs first road statute, the 1666 Act for Making High Wayes, directed each county court to select, clear, and maintain âÂÂhighways,â funding the work through compulsory labor or tobacco levies.
The 1696 Act for the Better Clearing of the Roads reaffirmed those obligations but still provided no dedicated cash revenue.
As overland commerce expanded after the Revolution, the General Assembly in 1787 authorized tolled, 66-foot-wide roads from Baltimore toward Frederick, Reisterstown (with branches to Westminster and Hanover), and York, prescribing surfacing standards and gate spacing while leaving construction to county commissioners.
That hybrid public-oversight/toll-revenue model became the legal framework for the chartered turnpike companies listed below.
The Monocacy Road and Nemacolin's Path were Indigenous thoroughfares later adapted for colonial traffic. The Monocacy was widened for wagons by 1739. It linked the Potomac crossing at Conococheague Creek with Frederick, York, and Lancaster, demonstrating the commercial value of improved inland corridors.
Military activity pushed construction westward when George WashingtonâÂÂs militia (1754) and General Edward BraddockâÂÂs expedition (1755) opened a graded track from Rock Creek to Wills Creek. Braddock's Road became the first engineered route across MarylandâÂÂs Allegheny Front and later guided both the Cumberland Turnpike and the federally funded National Road.
When Congress revisited the alignment a half-century later, its commissioners debated âÂÂhow best to engineer the routeâ across the same âÂÂirregular hills and hollows,â acknowledging that the terrain posed an âÂÂengineering challenge to road making.âÂÂ
Subsequent acts in 1796 and during the 1804âÂÂ05 session incorporated more than forty turnpike trusts and joint-stock companies to rebuild the 1787 lines and extend new toll roads. However, one-third of the corporations chartered never built anything due to an inability to raise capital.
After a period of intensive chartering in the 1810sâÂÂ1820s, Maryland's tollâÂÂroad network reached its zenith in the midâÂÂ1820s. At this peak, seven principal macadam turnpikes radiated from Baltimore-Reisterstown, York, Falls, Frederick, Washington, BelàAir, and HavreâÂÂdeâÂÂGrace, forming a spokeâÂÂandâÂÂhub network that funneled produce and passengers to the port city. Thereafter, most pikes functioned primarily as feeders to the expanding railways. A legislative tally in 1899 still recorded fifty-one chartered companies collecting tolls on about 497àmiles (800àkm) of road, roughly oneâÂÂquarter of the state's mainâÂÂroad mileage, while many other pikes had already reverted to county supervision. Seeking to modernize the fragmented system, the General Assembly created the State Roads Commission in 1908; between 1909 and 1918 the commission purchased or condemned the surviving franchises, and by the early 1920s virtually every turnpike mile had been rebuilt as a free public highway.
The principal alignments, most prominently the Baltimore-Frederick corridor, remain embedded in todayâÂÂs U.S.àRouteà40 and MarylandàRouteà144.
