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.
Louisiana Highway 97
Although no major changes have been made to the route of LA 97 since its creation, there have been several improvements. Shortly following the 1955 renumbering, a series of right-angle turns were smoothed out, most notably between Redich and Basile in Acadia Parish. By the 1980s, the portion of Main Street in Jennings carrying US 90 was returned to local control. The highway was realigned to follow the parallel Cutting Avenue co-signed with LA 102, and the southern terminus of LA 97 was then moved three blocks east to its present location. The bridge across Bayou Nezpique at the Jefferson Davis–Acadia parish line was replaced around 1990. An additional improvement occurred when I-10 was constructed through the area in the early 1960s. The interstate was opened to traffic eastward from Jennings to Crowley in March 1963, partially opening the interchange with LA 97. The interchange was completed with the opening of the section from Jennings westward to Welsh two years later.
