Interstate 195 (Maryland)

Interstate 195 (I-195) is an auxiliary Interstate Highway in the US state of Maryland. The highway runs 4.35 miles (7.00 km) from I-95 in Arbutus east to Maryland Route 170 (MD 170) near the Baltimore/Washington International Airport (BWI Airport) in Linthicum. I-195, which is also known as Metropolitan Boulevard, is the main connection between the airport terminal and highways leading to Baltimore, Washington, D.C., and Annapolis, including I-95, MD 295, and I-97. The interchange with MD 170, which forms part of the Airport Loop, provides access to various airport-related services. I-195 also links I-95 with Catonsville and the University of Maryland, Baltimore County (UMBC), via a westward continuation of Metropolitan Boulevard that is part of MD 166.

I-195 was constructed in three sections. The first section was a connection between MD 295 and the airport. This segment was built as Maryland Route 46 (MD 46) and completed in 1951 shortly after the opening of the airport, which was originally named Friendship International Airport. The second segment was completed at the opposite end of the highway in the mid-1970s, connecting U.S. Route 1 (US 1) and I-95 with MD 166 and UMBC. The first two segments were connected when the portion between MD 295 and US 1 was constructed in the late 1980s. The whole length of the highway was completed and was marked as I-195 in 1990. In 2015, the eastern terminus was cut back from the airport to MD 170, with the former section between those two points becoming MD 995A.
