Interstate 170 in Maryland was a planned spur to downtown Baltimore from Interstate 70 in the Western portion of the city. It was approved by AASHTO on June 30, 1970.
Since Interstate 70 was never constructed in Baltimore, Interstate 170 was never completed to its planned western terminus. However, a small segment of the intended Interstate 170 freeway was constructed near downtown Baltimore. Once it was determined that Interstate 70 would never be built in the city, the orphaned Interstate 170 freeway was downgraded to a portion of U.S. 40.
