Interstate 195 provides a high speed route to the passenger terminal of Thurgood Marshall Baltimore-Washington International Airport (BWI) from Interstate 95 at Arbutus. The freeway also comprises a commuter route with connections to Baltimore-Washington Parkway (Maryland 295), U.S. 1 and Maryland 170. The north end serves the University of Maryland – Baltimore County (UMBC) campus and 483 space park & ride lot at Catonsville.
The freeway for I-195 previously consisted of two independent sections. Designated as Maryland 46, the southern segment spurred south from a three-wye interchange at B/W Parkway to the newly opened Friendship International Airport in 1952. The northern route, posted as Maryland 166, connected I-95 south with U.S. 1 near Elkridge in August 1974 and north to the new campus of UMBC in 1975. Due to the cancellation of Interstate miles elsewhere in the state,1 AASHTO approved the designation of Interstate 195 from I-95 and Maryland 166 southeast to BWI Airport on November 15, 1975.
Efforts to complete the 1.5 mile long section linking the two freeways were delayed by an extended environmental review process needed for the stretch through Patapsco Valley State Park and a focus on construction funds elsewhere in the state. The route was ultimately completed on June 20, 1990, as were upgrades to Interstate standards on the original MD 46 section.1
A $1 million project overhauled the Catonsville park and ride lot at the north end of Interstate 195 from June to fall 2012. The work shifted the Rolling Road entrance to lie adjacent to the park and ride exit and left-hand turn from I-195 to Rolling Road south. A traffic light was installed there as well. Additional work removed 25 spaces at the northern portion of the lot to accommodate new green space.2
A short section of Interstate 195 was withdrawn from the Interstate System by request of the Maryland Department of Transportation on September 1, 2015. This removed I-195 from south of Maryland 170 (Aviation Boulevard) to the Thurgood Marshall Baltimore-Washington International Airport (BWI) terminal area. The withdrawal was approved by the Federal Highway Administration. An eastbound confirming marker was posted beyond MD 170 in 1993. Eastbound end signs were added beyond the interchange by 2010.
