Question: does the silver line go to logan airport

Answer: Yes, The first section has two routes from Dudley Square in Roxbury, mostly via Washington Street, to Boston's Downtown Crossing (SL5) and South Station (SL4), using articulated buses operating in reserved lanes. The second section runs from South Station Under to Logan Airport in East Boston (SL1), South Boston (SL2), and to Chelsea via the Chelsea Street Bridge (SL3). The second section runs dual-mode buses, partly in a dedicated bus tunnel and partly on shared roadway, including surface streets, the Ted Williams Tunnel, and airport roads. Riders can transfer between the sections and to other lines at South Station; transfers there between SL1, SL2, SL3, and the Red Line--but not SL4--are within fare control. A transfer between these lines and the SL4 can be made at street level just outside South Station.
