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.
Interstate 96
Since the completion of I-96 in 1977, several changes to the freeway have taken place. Beginning in 1984, an extension of the US 27 freeway (later to become I-69) bypassing Lansing opened; US 27 was then cosigned with I-96 along the western side of Lansing. Three years later, the I-69 designation was applied to this new bypass, resulting in a triple concurrency (I-96/I-69/US 27) that existed until 2002, when US 27 was decommissioned in Michigan.
From 2003 to 2005, the Beck Road interchange (exit 160) in Novi was reconstructed as a single point urban interchange (SPUI), the first in the metropolitan Detroit area and the first on I-96.
An interchange between 36th Street and I-96 was built starting in 2005 and was completed in 2006. The project aimed to improve access to the Gerald R. Ford International Airport southeast of Grand Rapids. The reconstruction of the Wixom Road interchange near Novi as a SPUI was completed in late fall of 2008. Another interchange at Latson Road in Howell was approved for construction on July 19, 2012. This interchange was designed to bring improved access to the eastern Howell area, which prior to construction of the Latson Road exit was only accessible from westbound I-96. The project was completed on December 2, 2013. Also in 2013, the two interchanges near Nunica serving M-104 and B-31 were reconstructed, with two ramps removed from the former and two added to the latter; a new partial interchange was also built in preparation of M-231, which opened on October 30, 2015.
