LocalLink 75 is a bus route operated by the Maryland Transit Administration in Baltimore and its suburbs.

The current Route 17 started operating in 1973 between downtown Baltimore and Gibson Island.

At that time, it served the Annapolis Road/Baltimore-Annapolis Boulevard and Mountain Road corridors, mostly of Anne Arundel County.

17 designation was previously used for a streetcar that ran along the St. Paul Street corridor of Charles Village from 1893 to 1938.

[6] When the Central Light Rail line was opened in South Baltimore and Anne Arundel County, Route 17 underwent a series of changes in various phases.

All service between BWI Airport and Lake Shore Plaza was eliminated, as MTA would no longer serve some of these communities.

In 2001, with the opening of Arundel Mills mall in Hanover, Maryland, Route 17 was extended to this area.

[10] Under this plan, riders between the airport and Arundel Mills were instructed to use Howard County Transit's Red Express Route, which operates along nearly the same route in this area, and all other riders in Anne Arundel County would lose service.

[11] The plan resulted in a public outcry from riders, businesses along the route, and community activists.

One of the major complaints was that many non-English-speaking riders along the route who worked within the BWI hotel district would lose service and not even know it.

Some of the deviations along the route where duplicate service is provided (such as to BWI Amtrak) would be eliminated or modified.
