How long is Interstate 97?
Interstate 97
I-97 temporarily gains two extra lanes in each direction between MD 100 and its partial cloverleaf interchange with MD 176 (Dorsey Road). Access from the southbound Interstate to MD 176 is via MD 162 (Aviation Boulevard), which forms part of the Airport Loop surrounding Baltimore–Washington International Airport. I-97 continues through Ferndale, where it crosses over the Glen Burnie branch of MTA Maryland's Baltimore Light RailLink immediately before the highway's four-ramp partial cloverleaf interchange with MD 648 (Baltimore–Annapolis Boulevard), which provides access to the transit line's terminal station, Cromwell / Glen Burnie station. I-97's final interchange is with I-695 (Baltimore Beltway). The Interstate crosses the Cabin Branch of Curtis Creek within the interchange, which includes a flyover ramp from I-97 to westbound I-695; that ramp and the one from eastbound I-695 to I-97 merge on the inside of the two carriageways of the Beltway. The Interstate drops to four lanes and reaches its northern terminus just north of the loop ramp from westbound I-695 to I-97 in Brooklyn Park. The highway continues as I-895A, a pair of ramps that merge with the spur from I-895 (Harbor Tunnel Thruway) to MD 2 (Governor Ritchie Highway). The continuation from I-97 includes a ramp to westbound I-695 that allows access to the Beltway's interchange with MD 648.[1][3]
