Interstate 97
Interstate 97 (I-97) is a part of the Interstate Highway System that runs entirely within Anne Arundel County, Maryland. The intrastate Interstate runs from U.S. Route 50 (US 50) and US 301 in Parole near Annapolis north to I-695 and I-895 in Brooklyn Park near Baltimore. The Interstate is the primary highway between Baltimore and Annapolis. I‑97 connects Annapolis with Baltimore–Washington International Airport and links the northern Anne Arundel County communities of Crownsville, Millersville, Severna Park, Glen Burnie, and Ferndale. It is the shortest primary Interstate Highway.

Reconstruction of the MD 3 divided highway and the Glen Burnie Bypass was a complex operation that involved many temporary openings, lane shifts, construction of new roadways, and reconstruction of existing roadways over several phases over several years. The first improvement was the reconstruction of the I-695 interchange between 1987 and 1991. The modern ramps from I-97 to westbound I-695 and from eastbound I-695 to I-97 were built, eastbound I-695's ramp over these two ramps was constructed, and the loop ramp from I-97 to westbound I-695 was removed. I-97 from its interchange with MD 648 to the new Beltway ramps was reconstructed to Interstate Highway standards and expanded to six lanes between May 1993 and August 1995. Part of the functionality of the loop ramp to westbound I-695 was restored in October 1995 when another ramp from the Harbor Tunnel Thruway approach to westbound I-695 was added to allow access from I-97 to MD 648.
