How big is Interstate 97?
Interstate 97
Despite the existence or upcoming construction of two divided highway corridors between Baltimore and Annapolis, a freeway connecting I-695 and US 50 was proposed as early as 1956 in the form of the Arundel Expressway, which would relieve congestion on MD 2.[25] The portion of the Arundel Expressway that is today MD 10 was constructed from I-695 to MD 648 in Pasadena between 1970 and 1978.[2] MD 10 was proposed to continued south of Pasadena as a toll road to US 50, but the section of the freeway south of MD 100 was removed from state plans by 1975.[26][27] MD 10 was completed to its present end in Pasadena in 1991.[25] The state of Maryland unsuccessfully petitioned the Federal Highway Administration for an Interstate designation for a Baltimore–Annapolis freeway after passage of the Federal-Aid Highway Act of 1968. However, the state was successful in obtaining Interstate mileage for the Baltimore–Annapolis corridor through the 1968 Howard–Cramer amendment, which provided for minor adjustments to the Interstate System if no additional costs were incurred.[28] Much of the mileage of what became I-97 was reallocated from canceled Interstate Highways in Baltimore and the Washington area.[29]
